[R] changing column labels for data frames inside a list

[Vikram Chhatre]

> summary(mygenfreqt)
                  Length Class  Mode
dat1.str 59220  -none- numeric
dat2.str 59220  -none- numeric
dat3.str 59220  -none- numeric

> head(mylist[[1]])
           1     2     3     4     5     6     7     8     9    10    11
 12
L0001.1 0.60 0.500 0.325 0.675 0.600 0.500 0.500 0.375 0.550 0.475 0.350
0.275
L0001.2 0.40 0.500 0.675 0.325 0.400 0.500 0.500 0.625 0.450 0.525 0.650
0.725

I want to change 1:12 to pop1:pop12

mylist<- lapply(mylist, function(e) colnames(e) <- paste0('pop',1:12))

What this is doing is replacing the data frames with just names
pop1:pop12.  I just want to replace the column labels.

Thanks for any suggestions.
