[R] Create new string of same length as entry in dataframe

[danobolg321]

I suspect that this is simple, but thanks in advance for any advice...

I have a dataframe, t2:

V1          V2
aaa         3
aaaa       4
aaaaaa    6
a            1
aa          2


V2 is the length of the string in V1 using  nchar(as.character(t1$V1))

I'd like to create a third column, that contains a string of the length of
V2, but containing an alternate text, e.g.

V1          V2     V3
aaa         3      bbb
aaaa       4      bbbb
aaaaaa    6     bbbbbb
a            1     b
aa          2      bb

or

V1          V2    V3
aaa         3     bad
aaaa       4     badb
aaaaaa    6     badbad
a            1     b
aa          2     ba  


Suggestions would be much appreciated!

Thanks.
