[R-pkg-devel] "try" malfunctions on Ubuntu Linux 16.04 LTS, R-release, GCC

Hello, All:


       devtools::check_rhub failed to trap an error wrapped in "try",
per the email below.  This came from running
devtools::check_rhub(Ecfun_dir), where Ecfun_dir = the path to a copy of
"https://github.com/sbgraves237/Ecfun".

       This is the development version of Ecfun, which I want to submit
to CRAN as soon as I can do so without offending the sensibilities of
the overworked CRAN maintainers.


       Suggestions?
       Thanks,
       Spencer Graves
