Split data.frame row into multiple rows based on commas

Question

I am attempting to split a row in a data.frame based on the character sequence \", \". Here\'s an example:

mydat <- data.frame(v1 = c(\"name,         


        

Answer 1

This should work.

install.packages("splitstackshape")
library(splitstackshape)
out <- concat.split.multiple(mydat, c("v1","v2"), seps=",", "long")


out
     v1 v2 v3
1:  name  1  1
2: name2  2  1
3: name3  3  2
4: name4  4  3
5: name5  5  3
