Hi Nicole,
The usual way something like this is done is to create a factor of a
given size with the appropriate levels:
party<-factor(sample(c("dem","rep","oth"),100,TRUE))
party
[1] dem dem dem rep oth dem dem oth rep dem rep rep oth dem oth oth
dem dem
[19] oth rep oth rep dem oth rep dem oth oth oth oth rep dem oth dem
oth rep
[37] dem oth dem oth rep oth rep oth rep dem dem rep rep rep dem oth
dem dem
[55] oth dem rep dem rep oth rep oth dem dem dem rep dem rep dem oth
rep rep
[73] rep dem rep rep rep dem oth oth oth rep oth rep oth oth dem oth
rep dem
[91] rep rep oth dem rep dem dem oth dem dem
Levels: dem oth rep
