package 'stats' in options("defaultPackages") was not found

[anayana]

Hey,

trying to use RCall I get stuck an already reported problem:

julia> using RCall
┌ Warning: RCall.jl: During startup - Warning message:
│ package 'stats' in options("defaultPackages") was not found
└ @ RCall C:\Users\abc\.julia\packages\RCall\0ggIQ\src\io.jl:172

Eventhough I found some discussions on that issue, I was not able to fix it.

• julia, R and RTools were updated.

• environmental variables were set

julia> ENV["RTOOLS44_HOME"] = raw"C:\rtools44\usr\bin"
"C:\\rtools44\\usr\\bin"

julia> ENV["R_HOME"] = raw"C:\Program Files\R\R-4.4.2"
"C:\\Program Files\\R\\R-4.4.2"

• some other approaches mentioned in the other discussions on that issue were tried.

My first idea was that julia might not access the correct R library, as there are 2 R libraries on my system, however the path to the library seem to be correct. In both libraries stats.dll file exists.

Does anybody has a hint how the problem could be fixed?

In terms only of trying different approaches, you could give specifying the path to the R environment through the preferences system a try.

I wonder if this is a BLAS issue -- it seems that BLAS loading issues can lead to errors with loading `stats. xref
