Dear R-devel list,
I maintain two packages that use Rust code through the "extendr" library:
ymd (https://github.com/shrektan/ymd) and fcl (https://github.com/shrektan/fcl)

These packages are currently at risk of being removed from CRAN due to calls
to R's non-API functions.

Hi all,
I met a problem with R-2.10.1 installation on AIX5.3.
The error message is as following:

Hi
I have managed to link R.dll to my Visual Studio Win32 GUI project. However
I am unable to see any of the R messages on a console.
I'm hitting a dead end trying to use R_tryEval.
Is there a way I can obtain the error message when R_tryEval fails?
Regards
Abhijit Bera

For the text based help, there is no search feature on Windows, e.g.
options(help_type="text");
help(readLines);
but if you use the HTML-based help, you can use the browser's search
features as suggested/wanted:
options(help_type="html");
help(readLines);

Hi
I'm getting the following errors while using the efficientPortfolio function
even though I'm setting the target return to the mean of the TargetReturn I
obtain from the portfolio object created by the feasiblePortfolio function.
First Error:
