Any expression that generates output can be wrapped in a call to hash. The usual output will be returned, with a hash character at the start of each line.

1	hash(x,char='#')

`x`	an R expression
`char`	text to prepend to each line

This is useful for embedding the result of an expression in a script.

used for side effects

Don't “hash” an expression that directly or indirectly calls a function being debugged. The debug output will be ‘sunk’ to a connection. If you get in this situation, recover by typing sink(NULL) until output is restored.
