I have genetic data as follows (simple example, actual data is much larger):
comb =
ID1 A A T G C T G C G T C G T A
ID2 G C T G C C T G C T G T T T
And I wish to get an output like this:
ID1 AA TG CT GC GT CG TA
ID2 GC TG CC TG CT GT TT
That is, paste every two columns together.
I have this code, but I get the error:
Error in seq.default(2, nchar(x), 2) : 'to' must be of length 1
conc <- function(x) {
s <- seq(2, nchar(x), 2)
paste0(x[s], x[s+1])
}
combn <- as.data.frame(lapply(comb, conc), stringsAsFactors=FALSE)
Thanks in advance!
