validMsg {Biobase}

R Documentation

Conditionally append result to validity message

This function facilitates constructing messages during S4 class validation, and is meant for developer rather than end-user use.

validMsg(msg, result)

`msg`	A character vector or NULL.
`result`	Any vector.

This function appends result to msg, but only if result is a character vector.

msg <- NULL
validMsg(msg, FALSE) # still NULL
msg <- validMsg(msg, "one")
validMsg(msg, "two")
