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

manisha
