How to store the console output to a variable in R

Question

In R I would like to store a console command to a variable. I have already tried with the solutions proposed in the following link but without luck: In R, is it possible to redirect console output to a variable? Here you are the command I'm using:

test <- capture.output(system("pa11y scuolafalconeborsellino.it; 
        perl -e \"print unpack('c', pack('C', $?)), \\$/\""), file = NULL)

The output visiblein the console is:

[4m[36m Welcome to Pa11y[39m[24m [90mWe'll sniff your page for you now. [39m [36m > [39mLoading page... [36m > [39mRunning HTML CodeSniffer... [36m > [39m[31mError: HTML CodeSniffer error[39m

-1

but the variable test is empty.

Thank you!

Answer 1

system has a parameter intern which can be used to save the output to a character vector:

test <- system("pa11y scuolafalconeborsellino.it; perl -e \"print unpack('c', pack('C', $?)), \\$/\"", 
               intern = TRUE)

Note that system2 is now prefered and system should be avoided in new code.
