I do not know how to use dput, i am attaching the txt file for the data http://r.789695.n4.nabble.com/file/n4222616/foo.txt foo.txt
c1<-read.dlim('foo.txt') c2<-c1 any_comp<-NULL for( i in 1:dim(c1)[1]) { num_comp<-0 for (j in 1:dim(c1)[2]) if (c1[i,j]==2) num_comp=num_comp+1 #"Y"=2 for (j in 1:dim(c1)[2]) if(num_comp>0) { if (data$t1d_ptype[i] == "T1D" && c1[i ,j] == 2) c2[i,j]<-"T1D_w" if (data$t1d_ptype[i] == "T1D" && c1[i, j] == 1) c2[i,j]<-"T1D_oc" if(substr(data$t1d_ptype[i],1,4) == "Ctrl" && c1[i,j] == 2) c2[i,j]<-"Ctrl_w" if (substr(data$t1d_ptype[i],1,4) == "Ctrl" && c1[i,j] == 1) c2[i,j]<-"Ctrl_oc" } else { if(data$t1d_ptype[i] == "T1D") c2[i,j]<-"T1D_noc" if(substr(data$t1d_ptype[i],1,4) == "Ctrl") c2[i,j]<-"Ctrl_noc" } } this gives me whether the particular t1d_ptype has a specific complication as well as there is another complication as well. I will appreciate help very much. thanks sharad -- View this message in context: http://r.789695.n4.nabble.com/Help-with-code-tp4218989p4222616.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
