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

[Plamen Mirazchiyski]

Thank you very much for your responses Duncan and Ivan.

I do not call .Internal(crossprod( ... )) directly. I use crossprod() 
just once in the entire package, the actual line of code is

unname(obj = crossprod(x = sweep(x = as.matrix(replicated.averages), 
MARGIN = 2, mean.replicate.averages, FUN = "-"))*des.scale.fac)

I followed Ivan's advice, built a binary package from source in R 4.3.1 
on Windows 10, then tested it on another Windows 10 machine with R 
4.3.1. The problem did not occur et all.

If I understand Ivan's email, my package should work on R 4.3.1, but 
what about newer versions? I checked some packages that were released 
today, e.g. abn, these were built by CRAN "using R Under development 
(unstable) (2023-10-24 r85407 ucrt)". Does this mean mine will fail on 
the current released version (4.3.1) if built by CRAN. As far as I see 
from the R Developer Page (https://developer.r-project.org), there is a 
new version (4.3.2) scheduled for October 31, 2023. Should I better wait 
until then?

Best,
Plamen
