Hi,
Either of these should work:
m<-matrix(c(".:0:0,0", ".:2:0,2", ".:194:193,1", ".:56:0,56", ".:58:50,8",
".:13:0,13", ".:114:114,0", ".:75:75,0"), nrow=2)
gsub("^\\.:[[:digit:]]+:","",m)
[,1] [,2] [,3] [,4]
[1,] "0,0" "193,1" "50,8" "114,0"
[2,] "0,2" "0,56" "0,13" "75,0"
gsub("^\\.:\\d+:","",m)
[,1] [,2] [,3] [,4]
[1,] "0,0" "193,1" "50,8" "114,0"
[2,] "0,2" "0,56" "0,13" "75,0"
A.K.

Subject: [R] R sub query
Hello,
I would like to substitute a substring of characters defined by a specific
start and end sequence.
i.e. in the example matrix below, I would like to substitute ".:X:" with "",
where X varies in sequence...
m<-matrix(c(".:0:0,0", ".:2:0,2", ".:194:193,1", ".:56:0,56", ".:58:50,8",
".:13:0,13", ".:114:114,0", ".:75:75,0"), nrow=2)
output required:
[,1] [,2] [,3] [,4]
[1,] "0,0" "193,1" "50,8" "114,0"
[2,] "0,2" "0,56" "0,13" "75,0"
Thank you for any help
Sarah
