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 [[alternative HTML version deleted]]
