Is there a shorter version for the folowing principle to rename certain columns of a data frame?

data1Names&         


        

Answer 1

You can use rename from the plyr package:

data1<-data.frame("a"=1:3,"b"=1:3,"c"=1:3)
> rename(data1,c('a' = 'hello','b' = 'world'))
  hello world c
1     1     1 1
2     2     2 2
3     3     3 3
