linux - R: cannot install 'rasclass' package on Ubuntu 14.04 -

-

i trying install 'rasclass' package on r (version 3.2.3) somehow installation fails. output large pasted here, found interested in this question, might key solve issue.

shortly: terminal can see have gcc-4.8 , 4.9, g++-4.8 , 4.9, , gfortran-4.8. remeber changing symbolic links between gcc , g++ use "4.9" version. can not having gfortran-4.9 problem? if so, how change symbolc links version after downloading?

finally, paste last part of (failed) package installation.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
