Hi Jun,
As you do seem to want to replace commas within, not between, strings, try gsub:
gsub(",",";",test[,1])
Jim
Dear list,
Say I have a data frame
test <- data.frame(C1=c('a,b,c,d'),C2=c('g,h,f'))
I want to replace the commas with semicolons
sub(',',';',test$C1) -> test$C1 will only replace the first comma of a
string.
How do I replace them all in one run? Thanks.
