Infinite degrees of freedom for F-distribution
This is just a suggestion/wish that it would be nice for the F-distribution
functions to recognize limiting cases for infinite degrees of freedom, as
the t-distribution functions already do.
The t-distribution functions recognize that df=Inf is equivalent to the
standard normal distribution:
> pt(1,df=Inf)
[1] 0.8413447
> pnorm(1)
[1] 0.8413447
On the other hand, pf() will accept Inf

Interpretation of escaped characters in \examples{}
I've noticed a curious interpretation of escaped characters in \examples{}
in .Rd files.
For example, if I type
files <- dir(pattern="\\.txt")
at the R prompt, I will get a vector containing all file names in the
current directory containing the string ".txt". If I put
\examples{ files <- dir(pattern="\\.txt") }
in an .Rd file of a package,

formal methods and classes and capitalization conventions
Martin Maechler has suggested that I post this comment to r-devel. It was
originally posted to bioconductor.
---------------------------------
I'd like to raise the issue of a capitalization convention for naming
objects in R. Almost everything in R used to be lowercase but recently
there is increasing use of mixed upper/lower case to define names. There is
potential for using the

Standardized Pearson residuals (and score tests)
Hi Peter and others,
If it helps, I wrote a small function glm.scoretest() for the statmod
package on CRAN to compute score tests from glm fits. The score test for
adding a covariate, or any set of covariates, can be extracted very neatly
from the standard glm output, although you probably already know that.
Regards

R CMD check: is it error to setMethod for class not currently defined?
Should R CMD check consider it an error to define a new method using
setMethod for a class which is not currently defined? It seems to me that
it would be best not to consider this an error.
What currently happens in that setMethod issues a warning, quite correctly.
This warning produces an object 'last.warning'. Then R CMD check issues a

Using a function from splines.c in our package
Dear all,
I'm writing to ask for advice as to best practice. A PhD student working
with me is writing C++ code that we hope to make public as src code in our
Bioconductor package edgeR. He wants to call the function fmm_spline,
which is part of the source code for the stats package
http://svn.r-project.org/R/trunk/src/library/stats/src/splines.c,
from his C++ code. This function

Rcmd check does not recognize formal generic function as code object
Dear all,
I am trying to write a package using formal methods and classes from the
methods package. I have not been able to get the package to pass rcmd check
without warnings, because rcmd check does not recognize my generic
functions as code objects and therefore queries why they have documentation
entries.
I have isolated the problem in a very small trivial example which I give
below. I

Will there be 2016 issues of The R Journal?
The R Journal home page doesn't make any promises about how frequently the
journal will be published. Historically, though, there have been issues in
June and December of each year. The June issue has always appeared by this
time (6 August) in previous years.
Has there been a change in the publication schedule? Are there still plans
for a June 2016 issue?
Thanks

Re: R-devel Digest, Vol 3, Issue 23
I am another person who has had trouble documenting S4 classes and
(particularly) methods. The methods package itself is pretty cool by the
way, but it is a pity that there are as yet no guidelines on S4 in the
"Writing R Extensions" document.
I have actually put together a guide on S4 documentation myself for the use

Confidence interval bars on Lattice barchart with groups
I am trying to add confidence (error) bars to lattice barcharts (and

Samba4 not able to write to group writeable folder???
Hi...
With samba4 I sometimes feel like a bloody beginner even I use samba

Miracle of the day: Users connecting using samba4 cannot write to group
writeable folders even they should be able to.
I upgraded one 3.6 fileserver to 4.2.3. PDC is always a samba 4.2.3
instance. I am using samba4 in classic PDC mode for a couple of reasons.

Reshaping data from long to wide without a "timevar"

I was wondering if it's possible to reshape data from long to wide in R without using a "timevar". I've pasted some sample data below along with some code. The data are sorted by Subject and Drug. I want to transpose the Drug variable into multiple columns in alphabetical order.

confusion about what to expect?
