Using the booktabs \midrule and with brackets - latex

I am having trouble using \midrule in a latex longtable along with brackets. For example, here is my latex document (test.tex):
\documentclass[a4paper]{article}\usepackage[]{graphicx}\usepackage[]{color}
\usepackage{longtable}
\usepackage{booktabs}
\begin{document}
\begin{longtable}{|l|l|}
\caption{} \\
\toprule
test & estimate\\
\midrule
(Intercept) & 10.000 \\
test & 20.000 \\
\bottomrule
\end{longtable}
\end{document}
When running pdflatex on this file:
pdflatex test.tex
I run into these errors:
! Undefined control sequence.
<argument> ...al \expandafter \let \cmrsideswitch
\#tempa \fi \fi
l.12 (Intercept)
& 10.000 \\
Removing the brackets fixes the issue. And interestingly switching the order of the 2 rows works too [i.e. the (Intercept) row as the second row). I can't figure out what is wrong. Has anyone encountered this?

OK, so I had the same problem with code generated from Pandoc (with bracket after \toprule), I fixed it by using \toprule{} instead, it seems that toprule eats the bracket otherwise. Maybe this will help you.
Another possibilty is to put empty \hbox{} before the opening bracket, which I used, since I could not modify tex produced by pandoc (but pandoc is capable of parsing latex snippets in markdown).

In latex how to escape "{" in \verb in tabularx environmnet?

I tried \verb|\{|, and it will print \{. If using \verb|{| without the backslash, an error would occur that says ! File ended while scanning \TX#get#body
Use the following to replicate this error on Overleaf or WinEdt:
\documentclass{article}
\usepackage{tabularx}
\begin{document}
\begin{table}
\begin{tabularx}{\textwidth}{ll}
\hline
\verb|{| & Error. \\ % The use of \verb|{| here generates the error!
\hline
\end{tabularx}
\end{table}
\end{document}
I the above code, "\verb|{|" will generate the error.
With the kind help from samcarter_is_at_topanswers.xyz, I understand now that "{" can be displayed in tabularx using \listinline{{}. But this gives a plain-text style "{". Is there a way to make the "{" more code style? See the below picture for comparison.
You can use the listings package:
\documentclass{article}
\usepackage{tabularx}
\usepackage{listings}
\begin{document}
\begin{table}
\begin{tabularx}{\textwidth}{lX}
\hline
\lstinline{\}} & Error. \\
\hline
\end{tabularx}
\end{table}
\end{document}

Table caption misplaced and no list of tables generated

I am writing an APA-style document in RMarkdown using Papaya package, which compiles into LaTeX, and then to pdf, by pandoc. I know a small amout of LaTeX, and I am not familiar with RMarkdown, and was asked to use it. So I have two problems here, and thank you in advance for any help. The problems might be related to Rmarkdown/Papaya, but they could also be purely LaTeX related, so even if you don't know about RMarkdown, you may still know something.
The first problem. I have the following table in my RMarkdown file,
\begin{center}
\begin{tabular}{| c | c | c | c | c | c | c |}
\hline
Model & Composability & Unboundness & Comm. & Sync. & Distribution & Mobility\\ \hline
$\pi$ & explicit & explicit & shared-mem & sync & NA & NA \\ \hline
Join & explicit & implicit & shared-mem & sync & implicit & implicit\\ \hline
Ambient & explicit & explicit & shared-mem & sync & explicit & explicit\\ \hline
Actor & NA & implicit & message-pass & async & implicit & implicit \\ \hline
\end{tabular}
\captionof{table}{Summary of Properties of Concurrency Models}\label{summary}
\end{center}
I was wondering how I can make the caption one-line and centered in the generated pdf file? It now spans two lines and is not centered (see this screenshot).
The second problem. I also would like to generate a list of tables after tables of contents. When I add \listoftables to the beginning part of the RMarkdown file together with other LaTeX command, \listoftables is missing from the generated .tex file, but the other commands shown below such as \newcommand are preserved in the .tex file.
```{r analysis-preferences}
# Seed for random number generation
set.seed(42)
knitr::opts_chunk$set(cache.extra = knitr::rand_seed)
```
\listoftables
\newcommand{\defeq}{\vcentcolon=}
\newcounter{equationset}
\newcommand{\equationset}[1]{% \equationset{<caption>}
\refstepcounter{equationset}% Step counter
\noindent\makebox[\linewidth]{Equation set~\theequationset: #1}}
\lstset{
basicstyle=\ttfamily,
mathescape
}
Then I notice there is an option at the beginning of the RMarkdown file
tablelist : no
and I change it to
tablelist : yes
but I get the following new compilation warning:
Warning message:
Package tocloft Warning: \#starttoc has already been redefined; tocloft bailing
out. on input line 1147.
The LaTeX packages that I included in the RMarkdown file are:
header-includes:
- \usepackage{amsmath}
- \usepackage{mathtools}
- \usepackage{listings}
- \usepackage{caption}

knitr file ended while scanning use of \#xverbatim

I have the following .Rnw file:
\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{multicol}
\begin{document}
\begin{multicols}{2}
\hskip-3.5cm\begin{tabular}{|l|}
\hline
\cellcolor[RGB]{0,0,140}{\large\textbf{\textcolor{white}{Bill To: }}}\\
\hline
\textbf{
"asdf"
}\\
\\[-1em]
\textbf{asdf#asdf.com} \\
\hline
\end{tabular}
\hskip6cm\begin{tabular}{|l|l|}
\hline
Date: & 05/31/2018 \\
\hline
Invoice \#: & 1234asdf \\
\hline
\end{tabular}
\end{multicols}
\end{document}
which gives me the expected pdf:
However, when I replace the "asdf" with R code:
\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{multicol}
\begin{document}
\begin{multicols}{2}
\hskip-3.5cm\begin{tabular}{|l|}
\hline
\cellcolor[RGB]{0,0,140}{\large\textbf{\textcolor{white}{Bill To: }}}\\
\hline
\textbf{
<<asdf>>=
cat("asdf")
#
}\\
\\[-1em]
\textbf{asdf#asdf.com} \\
\hline
\end{tabular}
\hskip6cm\begin{tabular}{|l|l|}
\hline
Date: & 05/31/2018 \\
\hline
Invoice \#: & 1234asdf \\
\hline
\end{tabular}
\end{multicols}
\end{document}
I get the following error:
File ended while scanning use of \#xverbatim
Looking at the generated .tex file, this is the relevant part:
\textbf{
\begin{knitrout}
\definecolor{shadecolor}{rgb}{0.969, 0.969, 0.969}\color{fgcolor}\begin{kframe}
\begin{alltt}
\hlkwd{cat}\hlstd{(}\hlstr{"asdf"}\hlstd{)}
\end{alltt}
\begin{verbatim}
## asdf
\end{verbatim}
\end{kframe}
\end{knitrout}
}\\
and this is what the .log file says:
Runaway argument?
#### asdf \end {verbatim} \end {kframe} \end {knitrout} \check#icr \expandafte
r \ETC.
! File ended while scanning use of \#xverbatim.
<inserted text>
\par
<*> test2.tex
I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.
! Emergency stop.
<*> test2.tex
What am I doing wrong?
By default, R output is wrapped in a LaTeX verbatim environment, and you can't put one of those inside \textbf. There are a couple of different approaches to fix this.
The simplest is just to use the chunk option results='asis', i.e.
\textbf{
<<asdf,results='asis',echo=FALSE>>=
cat("asdf")
#
}
This will prevent knitr from adding the environment around the output; the LaTeX code will just be
\textbf{
asdf
}
which should be fine.
If you want the default formatting but just want to change the font or style of text, things are harder. You need to tell knitr to use a different environment instead of verbatim, e.g. the Verbatim environment provided by the fancyvrb package. You can do this by changing the output hook. For example, this should work
% in the preamble:
\usepackage{fancyvrb}
<<include=FALSE>>=
oldhook <- knitr::knit_hooks$get("output")
bold <- function(x, options)
paste0("\\begin{Verbatim}[fontseries=b]\n", x, "\\end{Verbatim}")
#
% in the body:
<<asdf,echo=FALSE>>=
knitr::knit_hooks$set(output = bold)
cat("asdf")
#
% Optionally restore the old hook...
<<include=FALSE>>=
knitr::knit_hooks$set(output = oldhook)
#
However, it doesn't always work, because some options (like fontseries=b) conflict with settings that knitr makes. You can change to italic (using fontshape=it), but not to bold. So stick with the first suggestion.

How do I compile a LaTeX table exported from R?

I'm completely new to LaTeX and have the MacTeX 2009 package installed, with the intent of having tables from R output into LaTeX and formatted as PDF.
I get the following LaTeX code (below) when I run an example in R (it renders ok in R, but I´d like to use TeXshop). However, when I paste this into a TeXshop window, I get the following error:
./Untitled.tex:2: LaTeX Error: Environment table undefined
I´m sure there is something very basic I´m missing here.
% latex.default(cstats, title = title, caption = caption, rowlabel = rowlabel,
% col.just = col.just, numeric.dollar = FALSE, insert.bottom = legend,
% rowname = lab, dcolumn = dcolumn, extracolheads = extracolheads,
% extracolsize = Nsize, ...)

You need some boilerplate around this to set up the document -- the LaTeXTemplate in TexShop should do.
Your \begin{table} is commented out with a preceding %
There are some missing backslashes in the legend text -- possibly these are just cut & paste artefacts?
This thrown-together version works for me, though you may need to tweak it for your purposes:
\documentclass[11pt]{article}

\end{table}
\end{document}
If you use the package stargazer (available on CRAN), you can use the argument out="filename.tex" to output the LaTeX code directly into a Tex document. That document should then be easy to compile.
It sounds like you may not have a document class defined, or you are not using a document class that defines the table environment.

How to create a \newenvironment in latex for a scaled table

I try to define a table as a new environment.
\newenvironment{scaledtable}[1]{%
\begin{table}[h]
\caption{xxx}
\label{tab:xxx}
\begin{center}
\begin{tabular}{rcrrrrrrrrrrrrcc}
}{
\hline
\end{tabular}
\end{center}
\end{table}}
The problem I have is that I can't use scalebox{}. If I put the closing bracket into the end definition of the environment, latex can't assign the brackets anymore. I also can not use PStricks because of pdflatex.
Use \lrbox to temporarily store the table, then scale it
\newsavebox{\scaledtablebox}
\newcommand*{\scaledtablefactor}{1}
\newenvironment{scaledtable}[1]{%
\renewcommand*{\scaledtablefactor}{#1}%
\begin{table}[h]%
\caption{xxx}%
\label{tab:xxx}%
%
\begin{lrbox}{\scaledtablebox}%
\begin{tabular}{ll}%
}{%
\hline%
\end{tabular}%
\end{lrbox}%
%
\begin{center}%
\scalebox{\scaledtablefactor}{\usebox{\scaledtablebox}}%
\end{center}%
\end{table}%
}
Works like this (0.5 is the scale factor):
\begin{scaledtable}{0.5}
Hello & World! \\
\end{scaledtable}
