Extract letters from a column

Dear Jorge,

I gave me this result (below) since it defines starting from the forth
letter and ending 6th letter from the first element.
substr(tempdf$name, 4, 6)
[1] " Cr" "ad " "old"

I would like to have letters from first and second elements if possible.

Thanks for replying,

Steve

Dear SH,

Hmmm... what about

substr(tempdf$name, 4, 6))

?

HTH,

Dear list:

I would like to extract three letters from first and second elements
in one column and make a new column.

For example below,

tempdf = read.table("clipboard", header=T, sep='\t')
tempdf
              name var1 var2    abb
1      Tom Cruiser    1    6 TomCru
2       Bread Pett    2    5 BrePet
3 Arnold Schwiezer    3    7 ArnSch
(p1 = substr(tempdf$name, 1, 3))
[1] "Tom" "Bre" "Arn"

I was able to extract three letters from first name, however, I don't
know how to extract three letters from last name (i.e., 'Cru', 'Pet',
and 'Sch').  Can anyone give me a suggestion?  Many thanks in advance.

Best,

Steve
