The help page for Sys.putenv seems to indicate using a single "="
rather than the double "==". Could that be your problem?

I am trying to get the Rmetrics.org component package fBasics by Diethelm
Wuertz into a Debian package. Thanks to a lot of work by Diethelm, it is
_almost_ there. It fails 'R CMD check' for me if I do not have the TZ
environment variable set [1], yet works fine as long as I set TZ.
I figured I could patch this in R/zzz.R and do
## set a timezone if none found in environment variables or options()
if (Sys.getenv("TZ")=="") {
if (is.null(getOption("TZ"))) {
cat("No timezone information found, using default of GMT\n")
Sys.putenv("TZ"=="GMT")
} else {
cat("No timezone information found, applying option() value of",
getOption("TZ"), "\n")
Sys.putenv("TZ"==getOption("TZ"))
}
}
right before library.dynam("fBasics", pkg, lib) concludes .First.lib().
Now, even with that little patch, the R CMD check still fails. Which means
that the package could fail CRAN tests unless CRAN has TZ set. That is a bit
of a gamble I'd rather avoid.
What am I doing wrong here?
Thanks, Dirk
[1] There is a bit of a Debian tradition to, if in doubt, cover things via
a configuration file in /etc rather than an environment variable. I got
rather used to that, and like living without env.vars.
