Details

A "smart" source-code comment is an Rcomment, which start with a '#', but is followed by a single letter, then a single symbol and a second '#' and then an option character string, and there must not be any code before the comment on the same line. In summary, a smart comment line has format: ## . Example code with two smart comments (VComments): x <- 2 \#V1\# threshold=-1 \#Vc\# A v-comment log message cat("Hello world") which after compilation becomes x <- 2 verbose <- Verbose(threshold=-1) if (verbose) { cat(verbose, "A v-comment log message"); } cat("Hello world")
