[R] Partialy SOLVED Re: Problems with "pdf" device using "plot" "glht" function on "multcomp" library.

[Kenneth Roy Cabrera Torres]

Hi R users:

I found a workaround for the problem I posted today.

I simple use "Cairo" library, then I use CairoPDF() function,
and it works!!!

The reason maybe is the acrobat reader, because the "okular" reader
from Ubuntu Linux shows the graphics just right.

Thank you for your help and advice.

Kenneth
