In case the OP wanted to append columns, rather than rename existing
columns:
cbind(myData, var1=NA, var2=NA, var3=NA)
col1 col2 col3 var1 var2 var3
1 1 2 3 NA NA NA
2 2 3 4 NA NA NA
3 3 4 5 NA NA NA

Hi,
You could use ?paste()
colnames(myData)<-paste(colnames(myData),paste0("var",1:3),sep="_")
myData
# col1_var1 col2_var2 col3_var3
#1 1 2 3
#2 2 3 4
#3 3 4 5

Subject: [R] just a small variable-naming question
Hi all,
If I have this little data set:
myData<- data.frame(col1 = 1:3, col2 =2:4, col3 = 3:5)
myData
col1 col2 col3
1 1 2 3
2 2 3 4
3 3 4 5
and I want to add (not replace) the names var1, var2, var3 to the existing
col1, col2, col3, what is the right way to do that?
Thanks.
-Richard
