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}

When compiling, it warns about line

With the following message:
"Underfull \hbox (badness 10000)".
How do I fix this?
I had a similar issue, I solved it by removing any \newline or \\ at the and of every sentence that had nothing textual below.
For instance, two examples that causes that problem:
An example. \\
This is well used. \\
This line will cause the error. \\
(I'm a new paragraph) \\
Because there's nothing directly underneath.\\
The last line does NOT require a "newline".
This is a thid paragraph. \\
:D
The same is true for figures or similar
This is a line.
Putting a "newline", as here, before a \begin will cause the error. \\
\begin{figure}[h]

A quick and nice solution is to use package parskip, and instead of using \newline or \\ for line breaks, simply insert an empty line

By the way, to know why it happened, refer to this question on TeX Stack Exchange.
Instead of forcing an underfull box with \newline, you could simply leave an empty line to start a new paragraph:

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}

\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.

<*> 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.
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).
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.

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:

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.
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}
