[R] Extract lines from file

[arun]

Hi Utpal,
You can use the same script from my previous email.  


 Lines1<- readLines("groups.txt")
library(stringr)
res<-paste(gsub("(.*\\:).*","\\1",Lines1),unlist(lapply(str_match_all(Lines1,"or10\\|\\d+"),paste,collapse=" ")),sep=" ")
write.table(res,"res1.txt",row.names=FALSE,col.names=FALSE,quote=FALSE)
 Lines2<- readLines("res1.txt")
length(Lines2)
#[1] 4633
 head(Lines2)
#[1] "OG1: or10|1345 or10|387 or10|474"                      
#[2] "OG2: or10|1562 or10|1584 or10|1977"                    
#[3] "OG3: or10|1636 or10|1990 or10|2257 or10|2258 or10|2499"
#[4] "OG4: or10|600"                                         
#[5] "OG5: or10|1053 or10|2869"                              
#[6] "OG6: or10|2798 or10|568"   

A.K.
