Hi all,I have large compressed text tab delimited files,
I am trying to write efficient function to read them,
I am using gzfile() and readLines()
zz <- gzfile("exampl.txt.gz", "r") # compressed file
system.time(temp1<-readLines(zz ))
close(zz)
which work fast, and create vector of strings.
The problem is to parse the result, if I use strsplit it takes longer then
decompress file manually , read it with scan and erase it.
Can anybody recommend an efficient way of parsing large vector ~200,000
entries
