Hello,
First, two notes:
1. 'var' is a really bad name for a variable, it already is an R function.
2. Your matrix seems more like a data.frame. The difference is important
because data.frames by default coerce character strings to factors. I
have tried to make the code work if this is the case or not.
vr <- read.table(text="
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
", header = TRUE)
yes <- as.character(vr[, "Ref_Allele"]) != as.character(vr[, "Var_Allele"])
vr[yes, ]
Hope this helps,
Rui Barradas

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
