R help - Aug 2013 - 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

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

A.K.
