Remove all text before colon

Question

I have a file containing a certain number of lines. Each line looks like this:

TF_list_to_test10004/Nus_k0.345_t0.1_         


        

Answer 1

I was working on a similar issue. John's and Josh O'Brien's advice did the trick. I started with this tibble:

library(dplyr)
my_tibble <- tibble(Col1=c("ABC:Content","BCDE:MoreContent","FG:Conent:with:colons"))

It looks like:

  | Col1 
1 | ABC:Content 
2 | BCDE:MoreContent 
3 | FG:Content:with:colons

I needed to create this tibble:

  | Col1                  | Col2 | Col3 
1 | ABC:Content           | ABC  | Content 
2 | BCDE:MoreContent      | BCDE | MoreContent 
3 | FG:Content:with:colons| FG   | Content:with:colons

And did so with this code (R version 3.4.2).

my_tibble2 <- mutate(my_tibble
        ,Col2 = unlist(lapply(strsplit(Col1, ':',fixed = TRUE), '[', 1))
        ,Col3 = gsub("^[^:]*:", "", Col1))
