Hi,
I am trying to format some data (example matrix "m" below) for which each data point has 2 associated values separated by a comma.
I want to replace values <3 with "0" to give the example output below. 
I have got as far as:
out<-lapply(strsplit(m,","),as.numeric)
Failed to identify anything along the lines of "[out<3]<-0" that works...
Thank you for any help!

m<-matrix(c("1,6", "0,12", "130,12", "0,0", "123,4", "2,2","3,7","9,6", "0,0", "12,2", "1,2", "0,3"), ncol=4)

required output:
     [,1]     [,2]    [,3]  [,4]  
[1,] "0,6"    "0,0"   "0,7" "12,0"
[2,] "0,12"   "123,4" "9,6" "0,0" 
[3,] "130,12" "0,0"   "0,0" "0,0"
