Hi,

strsplit(sub("(.*)(\\|.*)","\\1 \\2",test), " ")[[1]]
#[1] "comp99810_c0_seq1" "|m.8409"
 
sub("(.*)\\|.*","\\1",test)
#[1] "comp99810_c0_seq1"
 sub(".*(\\|.*)","\\1",test)
#[1] "|m.8409"

Hi Could some one help me regular expression for this. I am really struggling. 

Basically i want to write a regular expression to separate the string into two sub strings. 

For example in the example i want to separate the full string into "comp99810_c0_seq1" and "|m.8409". 

test <- "comp99810_c0_seq1|m.8409" 
c1 <- sub("([A-Za-z1-9])(\\|)(m.\\d+)", "\\1", test) 
c2 <- sub("([A-Za-z1-9])(\\|)(m.\\d+)", "\\2\\3", test) 

I was able to get c1 to work but not c2. Can somebody help me.... 

Thanks
