Hi,
Martin M. helped me focussing the context of my question. The main
result of my trials (various R4.x installations) after his mail is that
the warning is issued when using *devtools* to install a package *from
github*. When installing a package with install.packages(), no warning.
The warning looks like:
devtools::install_github("i-cyto/cytoBatchNorm")
WARNING: Rtools is required to build R packages, but no version of
Rtools compatible with R 4.2.1 was found. (Only the following
incompatible version(s) of Rtools were found: 4.0)
Please download and install Rtools 4.2 from
https://cran.r-project.org/bin/windows/Rtools/ or
https://www.r-project.org/nosvn/winutf8/ucrt3/.
Downloading GitHub repo i-cyto/cytoBatchNorm@HEAD
...
I don't think there is a need of Rtools. Let me know if you think there
is a need of Rtools being installed prior to installing a pure R
package. From your answers, I may contact the maintainer of devtools.
Thanks for reading.
Bonne journée,
Samuel
