Dear R-gurus,
Just supose I have a dara.frame that looks like
myDF<-read.table(stdin(),head=T,sep=",")
codID,namesp,k1,k2,k3,k4
1,spA,2,5,6,3
2,spB,4,5,4,6
3,spC,2,1,5,6
4,spC,5,4,3,2
5,spD,1,2,3,4
6,spE,2,4,3,1
I need to update the columns k1-k4 with the namesp, but
considering the math between Kx and codID.
My desired output must looks like:
codID,namesp,k1,k2,k3,k4
1,spA,spB,spD,spE,spC
2,spB,...
3,spC,...
4,spC,...
5,spD,...
6,spE,...
Any help are welcome.
cheers
milton
