I've been building, checking, and installing a package all day today
with no errors. I have even been able to bring the package into R on my
machine and use it all day doing test runs.
However, now, when I run Rcmd check, I get errors. Keep in mind not one
thing has changed. I haven't touched any of the functions or .Rd files,
yet I get the error below at this point and the package cannot be built.
Why on earth would this error arise now when there were no problems at
all. The log says the error is with the function choose.M which uses
another function posterior. However, both of the functions work properly
when I source them in to R. More importantly, they worked properly when
I built the package an hour ago and brought the library into R.
