[R-pkg-devel] Building fails with 'mypackage/DESCRIPTION' does not exist

[Steve Gutreuter]

First, thank you Bill Dunlap, Peter Dalgaard and Max Turgeon,

I edited (incompletely) the initial posting and failed to change screenr 
to mypackage.  However that was not the source of the problem.
Windows sysadmins cannot be convinced that paths containing white space 
are pure evil, but that is also not the problem because building also 
fails on a Linux Mint box that uses only sane file/directory names.
Default installation from GitHub (sgutreuter/screenr) succeeds because 
the version in Master is OK.  The version in branch fixROC fails.

I think that the root of the problem is that the Rd files are not being 
created in /man.  Roxygen2::roxygenize() is failing *silently* (another 
source of frustration).  So I suspect the problem lies somewhere in the 
comments for one or more of the functions.  I am trying to identify 
where from a diff, as Bill suggested.

Best regards,
Steve
