[R-pkg-devel] "crossprod" is not a BUILTIN function
The sources show that crossprod has become a primitive function. I don't think this should affect any R code that calls crossprod(); are you trying to call .Internal(crossprod( ... )) directly? This was in the news a few weeks ago: "The matrix multiplication functions ?crossprod()? and ?tcrossprod()? are now also primitive and S3 generic, as ?%*%? had become in R 4.3.0." Duncan Murdoch

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
