I have installed 'ggplot2' using
install.packages("ggplot2")
on the R Console.
On F# side,
open RProvider.ggplot2
is not able to locate the namespace.
Not sure how to proceed.

I'm using Delphi CE 10.4, and it has the DCC32.exe disabled line compilation.
I'm trying to manually install Jedi components, in the readme of JCL it says that it's needed to open and edit included file to customize options, in my case, source\include\jcld27win32.inc.
I'm starting to learn Delphi, and I didn't understand whats is it is necessary to do in this file, and didn't find videos showing a manual installation.
Someone who already installed this way could help me?
Manual Installation Although it is not recommended, a manual
installation is possible. You will have to manually configure options
for the library. That is done by modifying an included file. For each
tool you want to install the JCL in, repeat the following steps:
Open and edit included file to customize options: ... For Delphi 10.4 and C++Builder 10.4 Win32: source\include\jcld27win32.inc ...
In the IDE, open and compile package Jcl.dpk (or Jcl.bpk for C++Builder) located in a subdirectory of the "packages" directory
matching your version of the IDE. This package doesn't have to be
installed since it doesn't provide any components.
If you want to install experts, open package JclBaseExpert.dpk and compile it, then you can install all the experts you want (packages
are located in the same directory).
I'm trying to install some nuget packages using vs code in F# interactive (fsx script). It has worked before because I have successfully installed FSharp.Data, but it seems to not work (anymore).
Following error
No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages, nuget.org (vs code)
Code
open System.IO
open System
Environment.CurrentDirectory <- __SOURCE_DIRECTORY__
#r "nuget:System.Data.Linq.dll"
#r "nuget:FSharp.Data.SqlClient.dll"
A related issue says to list the nuget sources through commandline:
Visual Studio 2019 F# NU1101 Unable to find package FSharp.core
When I do this I get a correct response:
So what is going on here?
When You use nuget prefix in the #r directive, you don't have to add ".dll" extension at the end of package name. It is required only when you are referencing local dlls.

I'm going to create Q# application for the first time. I installed the "Microsoft Quantum Development Kit" and I have .not core 3.1.301 (the latest)
I use VS 2019 Community Edition.
In VS, I see the Q# Application when creating new solution but when I try to create , I get below error:
The project file cannot be opened by the project system, because it is
missing some critical imports or the referenced SDK cannot be found.
Detailed Information: The SDK resolver "NuGetSdkResolver" failed to
run. Unable to find fallback package folder
'C:\Microsoft\Xamarin\NuGet\'.
C:\Program Files\dotnet\sdk\3.1.301\Sdks\Microsoft.Quantum.Sdk\Sdk not
found. Check that a recent enough .NET Core SDK is installed and/or
increase the version specified in global.json.
I could not find any solution over the web.
The Quantum.SDK is not distributed with the extension, instead is downloaded the first time you try to build/create the Q# application.
Looks like Visual Studio is having problems downloading it using NuGet. I can think of two reasons:
1. You are not connected to the internet, so it can't connect to nuget.org to download the package
2. The error points to a missing "C:\Microsoft\Xamarin\NuGet\", I would suggest creating this folder.
I am currently learning F# and working through the samples on tryfsharp.org. I am using the Mono F# on a Mac.The script begins as follows:
#r "MathNet.Numerics.dll"
open MathNet.Numerics
open System.Numerics
When starting the script I get the following error message:
/Users/benjamin/Desktop/Kalman/kalman.fsx(1,1): error FS0078: Unable to find the file '
MathNet.Numerics.dll' in any of
/Library/Frameworks/Mono.framework/Versions/3.0.12/lib/mono/4.5
/Users/benjamin/Desktop/Kalman
/Library/Frameworks/Mono.framework/Versions/3.0.12/lib/m
I do not know, where to find that DLL or how to install it.
You should just be able to use nuget to get that library.
http://nuget.org/packages/MathNet.Numerics
See here to install nuget:

I know this might be a simple question but i searched the internet and couldn't find an answer. I am trying to install OExport - XLSX/ODS native Delphi/Lazarus import/export library http://www.kluug.at/xlsx-ods-delphi.php , but in order to install it I need to have prior installed OmniXMl. So I have downloaded from here http://www.kluug.at/xlsx-ods-delphi.php as well. I have extracted the archive and I opened from the dpk folder the OmniXml_Dxe2 package. And in the Delphi IDE i know that i need to right click on the project name (respectively OmniXml_Dxe2.bpl ) and then click install; but install option is missing (attached a picture); Then I thought that i need to run the project instead. So I when I run the project an error appears "Cannot run project unless a host application is defined. Use the Run|Parameters..dialog..box"
Could somebody please tell me where I am doing something wrong and what should I do in order to install OmniXml
The error you are seeing is because you are making a DLL or package, and they cannot be run. They only run when a host application is loading them, and you can use the Run/Parameters dialog to set this. But I suggest that you are really looking for the "Install" option for the project to load it as a package into Delphi.
