Hi 

 

 

   I just installed R  2.5 using R-2.5.0.dmg in Mac OSX 10.4.8 with framework
installed under /Library/Frameworks/R.framework

When I downloaded the R-2.5.0.dmg it also cam ewith a Packages folder
containing:R.GUIpkg,R-Framework Pkg, tcltk.pkg,gfortran.pkg.

But its  giving me an error as follows:

 

bic:/Users/toor root# R

I have another version of R in it under /usr/Frameworks/R.Framework for
R2.1.0(which worked fine) 

 

But investigators here want to use R2.5.0.

Please advice me out on how  can I remove these errors.
