How can I use awk in R

Question

I try to use awk to extract from a dataframe, but I get this message

    could not find function "awk"

Do I need to install a package?

Answer 1

Awk is a system command you need to call out of your R environment to the operating system and execute the awk command.

Example from R console

> system( 'awk \'BEGIN { print "Hello, world" }\' ')
Hello, world
