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

For posterity, users with an inclination for tidyverse packages can use tidyr's separate_rows function along with select from dplyr (to maintain the order of the columns) to get this done:

library(tidyverse)

mydat %>% separate_rows(v1,v2,sep=", ") %>% 
        select(v1, v2, v3)

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