[R-pkg-devel] "crossprod" is not a BUILTIN function

[Plamen Mirazchiyski]

Dear All,

Today I was preparing a new version for the RALSA package. I have built 
a Windows package using "devtools::check_win_devel()". I took the built 
Windows package and tested it on a Windows 10 machine to see if 
everything works as intended before submitting the source to CRAN. The 
machine has R 4.3.1, the latest official release. After I load the test 
RALSA package, R displays a message saying "Package RALSA built under R 
version 4.4.0", I guess this is what the win-builder uses when the 
source is sent via "devtools::check_win_devel()".

When testing one of the functions of the newly built RALSA package 
(lsa.corsstabs"), it crashes with the following message:

     Error in crossprod(x = sweep(x = as.matrix(replicated.averages),
     MARGIN = 2, : "crossprod" is not a BUILTIN function

I checked if it is a builtin by:

     grep(pattern = "cross", x = builtins(), value = TRUE)

This returned:

     [1] "tcrossprod" "crossprod"

I am not sure I understand, the "crossprod" function is in the base 
package and is builtin in 4.3.1, is it dropped in 4.4.0? If yes, how to 
overcome this?

Please advise.

Best,
Plamen
