For adding the 'names', put the data in a temporary first:
for(i in 1:length(seq.num)) {
k<- seq.num[i]
name.num<- names(file)[k]
temp <- fac2list(file[,k], file[3])
names(temp) <- levels(factor(file[[3]]))
assign(paste(names(file)[3], name.num, sep="_"), temp)
}
#I couldn't make it work
with get() either
