Comma separated string split

Question

I'm trying convert this vector string

a<-c("1,2,3","344")

into this

a<-c("1","2","3","344")

I'm using the following code:

a<-c("1,2,3","344")

b<-strsplit(a, ",")

c<-sapply( b, paste0, collapse=",")

But I'm getting back to the original vector:

c<-c("1,2,3","344")

Any help would be appreciated.

Thanks,

Albit

Answer 1

Try:

a <- c("1,2,3","344")
scan(text = a, sep = ",", what = "")
# [1] "1"   "2"   "3"   "344"

Answer 2

This solution is identical to the one on my comment:

a <- c("1,2,3", "344")
b <- unlist(strsplit(a, ","))
b
[1] "1"   "2"   "3"   "344"
