How to transpose it in a fast way?
...e that
AA CC ............
AC CC............
AA CT.............
AA CT.........
....................
....................
AT TC.............
The keypoint is I can't read it into R by read.table() because the
data is too large,so I try that:
c<-file("silygenotype.txt","r")
geno_t<-list()
repeat{
line<-readLines(c,n=1)
if (length(line)==0)break #end of file
line<-unlist(strsplit(line,"\t"))
geno_t<-cbind(geno_t,line)
}
write.table(geno_t,"xxx.txt")
It works but it is too slow ,how to optimize it???
Thank you
