Dear all,
I have a question regarding the R-devel version of .make_numeric_version()
function. As far as I can understand, the current code
(https://github.com/wch/r-source/blob/66b91578dfc85140968f07dd4e72d8cb8a54f4c6/src/library/base/R/version.R#L50-L56)
runs the following steps in case of non-character input:
1. It creates a message named msg using gettextf.
2. Such object is then passed to stop(msg) or warning(msg) according to the
following condition
tolower(Sys.getenv("_R_CHECK_STOP_ON_INVALID_NUMERIC_VERSION_INPUTS_") !=
"false")
However, I don't understand the previous code since the output of
Sys.getenv("_R_CHECK_STOP_ON_INVALID_NUMERIC_VERSION_INPUTS_") != "false" is
just a boolean value and tolower() will just return "true" or "false". Maybe
the intended code is
tolower(Sys.getenv("_R_CHECK_STOP_ON_INVALID_NUMERIC_VERSION_INPUTS_")) !=
"false" ? Or am I missing something?
Thank you very much for your help
Kind regards
Andrea
