Hi all and thank you for your time. I would like to delete rows from this matrix I call "var" if the character in Ref_Allele is equal to the character in Var_Allele. I have attached a before and after, to help my poor explanation. If someone could provide me with some code, or some guidance I would really appreciate it.
Thank you again. "Before" > var Ref_Pos Ref_Allele Var_Allele Var_Freq 1 A A 100 2 T G 50 3 G G 100 4 G T 45 5 T C 80 "After" Ref_Pos Ref_Allele Var_Allele Var_Freq 2 T G 50 4 G T 45 5 T C 80 -- View this message in context: http://r.789695.n4.nabble.com/Delete-row-if-two-values-in-a-matrix-are-equal-tp4647554.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
