How do you paste list of items in R

Question

How do you paste list of items and get the result as shown below?

 mylist<- list(c("PDLIM5", "CBG"), c("PDLIM5", "GTA"), "DDX60")

result

PDLIM5:CBG  PDLIM5:GTA  DDX60

Answer 1

The pipe-friendly tidyverse equivalent with a map function from purrr:

library(purrr)
mylist %>%
  map_chr(paste, collapse = ":")

Answer 2

you can try:

sapply(mylist, paste, collapse=":")
#[1] "PDLIM5:CBG" "PDLIM5:GTA" "DDX60"   

The result is a vector.

If you want to further paste the result, you can do:

paste(sapply(mylist, paste, collapse=":"), collapse=" ")
#[1] "PDLIM5:CBG PDLIM5:GTA DDX60"
