I've written a small demo about it and published it here,
http://rpu
about length-0
expressions in stopifnot().
Indeed, in the past, I had thought of "improving" stopifnot()
by giving a warning or even stop() for logical(0) expressions,
but I quickly dismissed that idea after some experiments.

Of course, I'm not a native English speaker, and my teacher(s) /

Ideally the above code would be replaced by simply
.Internal(dput(x, file, opts))

So, and as you see at every startup of R :
"R is a collaborative project with many contributors."
I'm willing to try "good-looking" patches.
(to the *sources*, *NOT* to a printout of the function in your R con
t;robustbase")
require("robustbase")
fm <- lmrob(Post ~ pre +IV1 + IV2, setting = "KS2014",
data=yourdataframe)
where recent research lead to the recommendation of setting="KS2014",
which indeed maybe relevant for "ANCOVA".

nd 'glm' methods are hidden.
Of course I do recommend reading the real R source code (which
also contains the comments and has some logical order in all the
function definitions),
but you can use stats ::: influence.lm
to show a version of the f
Please use R 3.2.4 or newer, notably for dummy.coef() which was
improved (made more generally working) for R 3.2.4, notably
thanks to my colleague Werner Stahel.

Googling about R problems often does not lead to the best
solutions.
In this case do
?plotmath
and see that you do *NOT* need to install any extra packages.
You do have 29 R packages installed with your R installation,
you already have several 1000s R fu

I doubt that you followed it correctly. Sarah's advise is
usually really very sound -- and your code below is *not* :

Short executive summary to all the nice explanations and
examples (by the other Martin M) below:
Yes, this is misinformation.
You should *NOT* set R_HOME in a (system wide / user) profile.
