I've followed as many threads as I can on this to resolve, but no luck. Simply can't install R package "rgl". I have Upgraded Ubuntu server 16 to R version 3.3.1.
PuTTY X11 proxy: Unsupported authorisation protocol
Warning in rgl.init(initValue, onlyNULL) :
RGL: unable to open X11 display
Warning: 'rgl_init' failed, running with rgl.useNULL = TRUE
* DONE (rgl)
I've tried these bits of advice: Error in installing rgl package error: installation of package ‘rgl’ had non-zero exit status
I have X11 working fine outside R: http://www.tomsitpro.com/articles/how-to-use-x11-forwarding,2-843.html
but still get the error above.
Thanks for any help,
S.
