Can anyone explain me the following behavior:
1:2/1
[1] 1 2
-- makes sense
1:2/matrix(1,1,1)
[1] 1 2
-- makes sense
1:2/data.frame(a=1)
a
1 1
-- why is this different?
Best,
Ott

'rowsum()' seems to add row names to the resulting matrix, corresponding to
the respective 'group' values. This is very handy, but it is not
documented. Should the documentation mention it so it could be relied upon
as part of API?

I am referring to base::rowsum(), not rowSums(). For some reason I cannot
access it's help on my computer but the online documentation (R-devel
version) states:
Value
A matrix or data frame containing the sums. There will be one row per
unique value of group

Thanks, Hadley for bringing this up:-)
I am teaching R and I can suggest 5 different definitions of 'vector':
a) vector as a collection of homogeneous objects, indexed by [ ] (more
precisely atomic vector). Sometimes you hear that in R, "everything is a
vector", but this is only true for atomic

I agree that
If by standard you mean commonly used/understood, though, I doubt

Apparently your username/password are wrong. Can you clone/push from other
repos?
You do not need authorization when cloning a public repo, so even incorrect
credentials may work (haven't tested this though). But for push you have
to have that in order.
I suggest you create ssh keys, upload
Sorry if this topic has been discussed earlier.
Currently, hist(..., log="y") fails with

I have done this using attributes:
fr <- function(x) { ## Rosenbrock Banana function
x1 <- x[1]
x2 <- x[2]
ans <- 100 * (x2 - x1 * x1)^2 + (1 - x1)^2
attr(ans, "extra1") <- 1:10
attr(ans, "extra2") <- letters
ans
}
Not sure if this works in your case though.

I think part of the problem is that the corresponding section in "Writing R
extensions" is not very clear for newcomers. I admit I have read it
several times as I have been confused about the difference between suggest,
imports and depends, and so combed section 1.1.3 repeatedly. But from this
As I read the docs (a few months ago though), you are supposed to include
the pdf and encouraged to include sources, but the process to get pdf from
source may depend on your private libraries/data/software, and is not
replicated on CRAN checks. This seemed to work for me as my vignette
includes
Hi packagers,
what is the best way to skip certain tests on CRAN? So far I have included
certain test files in .Rbuildignore and run the tests on the package
directory. But now when moving to Authors@R format, I get errors about
missing maintainer etc.
I know there are options in testthat,
