[R-pkg-devel] discovering if a function in a package is called under RStudio

2018-02-09 Thread Georgi Boshnakov 
Hi,

Is there a canonical way for a function to discover if it has been called in a 
session under RStudio?
I looked the at the options() but none seems to be dedicated to this.

Thanks,
Georgi Boshnakov

Hi,

you can use rstudioapi::isAvailable() for that. There's other packages with
similar functionality (eg the assertive package), and you can always check
whether Sys.getenv("RSTUDIO") == "1".
Cheers

Many thanks, I should have looked at rstudioapi, from rstudioapi::isAvailable():

> .Platform$GUI
[1] "RStudio"

[R-pkg-devel] Hedgehog property based testing

2018-02-09 Thread Huw Campbell 
Hi all,

I have ported hedgehog, a property based testing library
 from Haskell to R, and would
really like folks to use it and test the API hard before I release it on
CRAN. I have been using it with great success for my projects for a while;
and have also uncovered a few real bugs in R libraries in the wild.

Hedgehog is similar to *quickcheck* in philosophy and fully compatible with
Hadley Wickham's *testthat* library, so should be easy to integrate. The
idea is to write property tests like this:

test_that("Reverse of reverse is identity",
  forall(gen.c(gen.element(1:100)), function(xs) expect_equal(rev(rev(xs)), xs))
)

Give it a shot and please do hit me up with any questions.

For all that I like about R, I think it can be tough to write robust
code which handles all the edge
cases one could throw at it, so great testing is invaluable.

Cheers,
Huw

Yes,

Thank you for the tips Suzen.

I will try to finish it in a couple of weeks from now, hope it is useful.

Kind regards,
