Dear Bioc team,

A friend of mine had the following trouble to install the biosigner package on 
R 3.2.3.

I do not understand why the package would require a dedicated version of R (in 
particular >3.2.3) except that it uses S4 methods, and if/how I have to specify 
an R version within the package (note that the ropls package, which biosigner 
depends upon, seemed to require also a recent version of R).

I thank you very much in advance for your answer.

Kind Regards,

Etienne.

Warning message:
package 'biosigner' is not available (for R version 3.2.3)

When I updated my R version to the latest it worked. I'll check which version 
is used in biosigner. But unless there is a good reason to have to use R > 
3.2.3, I would allow the package to install on older versions (people don't 
update R on their desktops so often). I think you need to set that up on the 
config files of the package that you upload to bioconductor.
