My feeling that everyone would index dataClasses by name was
wrong. I looked through the packages that used dataClasses
and saw code that would break if the first (response) entry
were omitted. (I didn't check to see if passing the output
of delete.response to these functions would be appropriate
I had noticed the same thing but figured that most
people (writers of predict methods) would be looking
up entries in dataClasses by name and not by position,
since predict's newdata argument need not have entries
in the same order as the data used to fit the model.
Hence the extra entry would not
I agree with almost all, except the last point. Since I have
participated in wheel-reinvention lately, I agree with the bulk of
your comment. I don't think the fix is as easy as you suspect,
RSiteSearch won't help me find a function I need when I don't know the
magic words. Some R functions have s
I posted this one as an R bug
(https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14767), but
Prof. Ripley says I'm premature, and I should raise the question here.
Here's the behavior I assert is a bug:
The output from delete.response on a terms object alters the formula
by removing the depende
Good stuff, Max!
Would also be nice to nail your 14 theses to a more permanent wall
than the r-help mailing list ... not sure where that would be, though
... isn't someone supposed to be redesigning the r-project.org
website? [I jest, I jest] More seriously, though, it might be worth
linking to fr
