[Bioc-devel] R environment variable which indicates "running in the bioc build system"?

[Paul Shannon]

Thanks, Herve.

How can I determine if a web browser is indeed installed?   

Sys.getenv("R_BROWSER”) returns:

 macOS: “/usr/bin/open”
 ubuntu: “xdc-open”

I don’t think either of these actually reveals an actual and functioning installation.

Other ideas?
