How to split comma separated values in an R vector?
The splitting of comma separated values in an R vector can be done by unlisting the elements of the vector then using strsplit function for splitting. For example, if we have a vector say x that contains comma separated values then the splitting of those values will be done by using the command unlist(strsplit(x,",")).
Example
x1<-sample(c("a,b,c,d,e,f,g,h"),30,replace=TRUE)
x1Output
[1] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" [5] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" [9] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" [13] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" [17] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" [21] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" [25] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h" [29] "a,b,c,d,e,f,g,h" "a,b,c,d,e,f,g,h"
