Hi all, I have a question about global and local variables.First of all, a variable defined in a for loop is it a local or global variable?? Second, I'm trying to build a loop in the following way: I have these 3 data frames bilanci_2005<-bilanci1[ANNO==2005,] bilanci_2006<-bilanci1[ANNO==2006,] bilanci_2007 <--bilanci1[ANNO==2007,]
LOOP: v=list(2005,2006,2007) for (a in v){ anno1=a anno2=a+1 for (i in 1:length(bilanci_a)) { assign(paste(""bilanci",anno1,anno2,sep=""), rbind(paste("bilanci",anno1,anno2, sep=""), bilanci_anno2[bilanci_anno2$CFISCALE==bilanci_anno1 [i,]$CFISCALE,], "bilanci_anno1[i,]) } } what I'm trying to do is for example to give the contents of a (so the values which are in the list named v) to the bilanci variable. In Stata this means using a particular kind of "". How can I do this in R? ______________________________________________ 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.
