HI,
"
btw, could this program be modified such that it take direct input from my
input.txt file???"
Lines1<-readLines("utpalmtbl.txt")
Lines1
#[1] "OG1: or10|1345 or10|387 or10|474 or11|1203 or11|182 or10|2158 or12|637"
#[2] "OG2: or10|1562 or10|1584 or10|1977 or11|2263 or11|43"
#[3] "OG3: or12|2400 or12|2401 or13|2697 or13|2698 or16|2 or16|914 or27|1355"
#[4] "OG4: or10|108 or20|2713 or25|2315 or25|2754 or2|1411"
library(stringr)
res<-paste(gsub("(.*\\:).*","\\1",Lines1),unlist(lapply(str_match_all(Lines1,"or10\\|\\d+"),paste,collapse="
")),sep=" ")
res
#[1] "OG1: or10|1345 or10|387 or10|474 or10|2158"
#[2] "OG2: or10|1562 or10|1584 or10|1977"
#[3] "OG3: "
#[4] "OG4: or10|108"
write.table(res,"res.txt",row.names=FALSE,col.names=FALSE,quote=FALSE)
Lines2<- readLines("res.txt")
Lines2
#[1] "OG1: or10|1345 or10|387 or10|474 or10|2158"
#[2] "OG2: or10|1562 or10|1584 or10|1977"
#[3] "OG3: "
#[4] "OG4: or10|108"
