Manisha -
Will this work instead?
if 'a' is your matrix, try
ifelse(a == "A", 0, 1)

Hello,
I will appreciate any suggestion for this simple problem. I have a matrix of
characters "A", "P", "M".
I want to convert those characters to integers 0,1, 1 respectively. I am
using the following R statements:
exprs.new<-gsub("P",1,exprs)
exprs.new1 <- gsub("A",0,exprs.new)
exprs.new2 <- gsub("M",1,exprs.new1)
The replaced integers are stored as characters and I cannot find a way to
convert the matrix to an integer matrix.
Thanks
