[R] Issue using tapply

Hello all, I am trying to use the tapply function to sum some values and change the column names of the resulting vector. I input Emp Et 1 10565 ACC 2 7515 ADM 3625 AGF 4 6243 CNS 5 12721 EDU 6 3924 FIN 7 18140 HLH 8 3686 INF 9 15841 MFG 10 243 MIN 11 1864 MNG 12

Re: [R] Issue using tapply

I think the problem is that there is no value for RST in Emp.Et.Em. -Ista On Mon, Jan 25, 2010 at 6:57 PM, LCOG1 jr...@lcog.org wrote: Hello all,   I am trying to use the tapply function to sum some values and change the column names of the resulting vector. I input     Emp  Et 1  10565

Re: [R] Issue using tapply

Try this: tapply(Emp.Et.Em[EtToEm..$Et], EtToEm..$Em, sum, na.rm = TRUE) On Mon, Jan 25, 2010 at 4:57 PM, LCOG1 jr...@lcog.org wrote: Hello all,   I am trying to use the tapply function to sum some values and change the column names of the resulting vector. I input     Emp  Et 1  10565
