it's slightly annoying to write
foo <- function(x) {
if ( ! is.numeric(x) ) stop("x should be numeric")
if ( ! length(x) == 2 ) stop("x should be length 2")
c(x[2], x[1])
}
i wonder if we could have some core functions that test the class and
the length in one and give the appropriate stop message.
maybe this exists already

Not sure about within Bioconductor but Hadley has a package to do this. https://github.com/hadley/assertthat On Wed, Jul 22, 2015 at 4:13 PM, Michael Love <michaelisaiahlove at gmail.com> wrote:

Also just found https://github.com/mllg/checkmate Haven't used it before but it seems well thought out, also impressive test coverage! (not biased). On Wed, Jul 22, 2015 at 8:47 PM, Valerie Obenchain <vobencha at fredhutch.org> wrote:
