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

Today I was preparing a new version for the RALSA package. I have built a Windows package using "devtools::check_win_devel()".
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"
Can you use R CMD build to make a .tar.gz source package and then
install that on the Windows 10 machine running R 4.3.1? There is
convenience and a lot of added value in both Win-Builder and devtools,
but it shouldn't be necessary to rely on 96 CRAN packages and an online
service just to build a package.
crossprod(x,y) has indeed been recently changed from
.Internal(crossprod(x, y)) to .Primitive("crossprod"). This makes it
possible for a binary package prepared using R-devel (with a call to
.Primitive('crossprod')) to misbehave on a released version of R (which
does have .Internal(crossprod(...)) but not .Primitive('crossprod')).
Installing from source will avoid this problem. So will building the
binary package using R-4.3.1 to run it on a different machine with
R-4.3.1.
