Hello,
I have a C function in which I want to return a result visibly or invisibly
(depends on the arguments provided). My current implementation was to
return a list like 'withVisible' does, where element "value" is the value
the function returns, and element "visible" is TRUE or FALSE depending on
whether the result is returned visibly or not. Something like:
{
value <- .External(C_fun, ...)
if (value$visible)
value$value
else invisible(value$value)
}
Is there a way to do this in C instead? Thank you!
