unit testing with model inheritence
Having jotted down some models, with some inheritence I tried to run some unit tests. After waiting for rake test_units to run I got a rake of errors (if you''ll forgive the play on words). The errors were to do with unknown tables in the tear down stage. The unknown tables corresponded to sub-types where single table inheritence was used. In other words, these tables *shouldn''t*

Always via logical expressions. In this case you can use the logical expression myDF$b != "0" to give you a vector of TRUE/FALSE B. > On Sep 25, 2017, at 8:00 AM, Shane Carey <careyshan at gmail.com> wrote: > > This is super, really helpfull.

REST / WS adapter for Rails

Or is not worth the effort because web services are so different from databases, even though they are typically data sources? Please reply to richardc@ASO.com. -- Richard Cunningham E-Mail:

Package nleqslv ERROR

Later, inside the function you assign to values to 4 elements of the vector "f". This assumes that "f" is at least 4 element in length. However, you define
