[RsR] Vote Concentration Equation

[Daniel]

Hello all,
I'm just a beginner on R issue, but improving.

Does anyone knows how can I get vote concentration to each ID by city
(CIDADE) considering each UF (State), because my data is long and has all
states together and IDs repeating across states.
I also tried to get  totals and then apply for division, but R din't allow
me to attach new column with less rows, of course.
So, someone have any light for me do that? Can I print values all without my
pain programing?

total.UF <- tapply(senador$Votos, senador$UF, sum)
total.MUN <- tapply(senador$Votos, senador$CODMUNIC09, sum)

z <- cbind(senador, total.UF)
Error in data.frame(..., check.names = FALSE) :
  arguments imply differing number of rows: 54861, 27

========= my data look likes these ===========
