[R] problems on JGR package and demo() function in Ubuntu linux
Dear R-helpers I want to express my respect and thankfulness to all of you. I have ever ask this question about one hour ago. Following Mr. Henrik Bengtsson's advice I re-submit this query here. I just switch from windows xp to Ubuntu linux platform. I am facingtwo problems when I run R in Ubuntu. I need your helps and advice, thanks in advance. 1.
