store output of system command into a variable in r

Question

I am executing the following command in R :

system("ls ") 

I need to store the output of the above command in some R variable. Is there a way to do the same??

Answer 1

Use intern=TRUE:

a <- system("ls ", intern = TRUE) 

Answer 2

why not use the corresponding R function?

a <- list.files() b <- list.files(recursive = TRUE) 

For more details

?list.files
