[Rd] does file.show() fail with multiple files ? (PR#13528)
Full_Name: giancarlo marra
Version: 8.1
OS: Windows Vista
Submission from: (NULL) (79.36.222.186)
When calling file.show() with, say, n different files, then n windows are opened
ALL with the same content from the first file of the list.
In my tests, it seems to work fine up to version 2.6.2, opening the n files in
the n windows, as documented. It appears broken starting from version 2.7.0.
Es.
file.show("example1.out","example2.out","example3.out")
opens three windows all reading examples1.out
The same if the call is in the form:
files=c("example1.out","example2.out","example3.out")
file.show(files, header=files)
In this case, the windows headers are correctly distinct, but the contents are
still the same from the first file.
Thanks.

Re: [Rd] sources of code; was Generate random numbers in Fortran
Ben Bolker gives some reasons why Numerical Recipes may be problematic as a starting point for R codes. CUP did a masterful job of marketing, but the license is restrictive as the links he gives points out. In some tests, I've also noted that some of the algorithms are less than stellar e.g, convergence tests in one or two optimization routines. Should we have a wiki item to help people find material? My own "Compact Numerical Methods: linear algebra and function minimisation" codes were first published 30 years ago this month. They are the Pascal library on Netlib. I have some Fortran codes I could post, and BASIC versions too. In fact, the function minimisation codes that are actually more advanced than the routines Brian Ripley used in optim() have already been made freely available (http://www.nashinfo.com/nlpe.htm). The codes still run right away in DOSBOX along with GWBASIC.EXE, but I believe the more useful aspect is providing methods and ideas. Gnu Scientific Library has been mentioned. It has some strengths but a number of "holes". There are some other notable collections. The Decision Tree for Optimization (Hans Mittelman) is a helpful link, though I am not certain all the resources are unencumbered. Would an annotated list of such openly usable resources be helpful? Perhaps if a couple of folk contact me off-list we can try a wiki item and see if it "works". JN __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

This is fixed in R-patched. The NEWS entry is:
o file.show() with multiple files would only show multiple
copies of the first one. (PR#13469)

[Rd] S4 structure classes and Ops methods
The methods package has methods for group generic "Ops" for S4 classes that extend "array", "structure" or "vector". The methods mainly try to produce a consistent result when structures and vectors are combined. See class?structure, section "Methods". In the development version of R committed today (r47924), these methods will be activated by loading any package with such classes. This was always the intention, but up to version 2.8.1, the methods were not activated UNLESS the package also defined some relevant methods itself. (Fixing this turned out to need a whole new mechanism, to indicate that the package needed the methods in question.) Note to package maintainers: if you have a package that defines such classes and does not define methods for operators, method selection may change for objects from these classes. In some cases, the new methods will be stricter (returning a vector result instead of mixing up attributes, for example, as the base code sometimes does). I haven't encountered examples, but please rerun CMD check if you think your package fits the description. John __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Re: [Rd] sources of code; was Generate random numbers in Fortran
I think something like this would be very useful. I'm sure you know of NIST's Guide to Mathematical Software (GAMS). It looks like they list places to find things, but it is clear some of that is proprietary (IMSL, NAG), some is on NETLIB but seems to have embedded copyright statements. (I once tried repeatedly to find out copyright info on an old routine from Bell Labs. I gave up after multiple e-mails and waiting weeks.) John ... John P.

[Rd] An inconsistency in docs for file.access(base)
I was chasing a "no permission to install to directory" error message. I was
looking in the code for /R/trunk/src/library/tools/R/install.R which pointed me
to the file.access function.
On reading the help for this function, it has the following in the Details
section:
The mode value can be the exclusive or of the following values
0 test for existence.
1 test for execute permission.
2 test for write permission.
4 test for read permission.
It has the following under the Examples section:
Examples
fa <- file.access(dir("."))
table(fa) # count successes & failures
d <- dir(file.path(R.home(), "bin"))
df <- dir(file.path(R.home(), "bin"), full.names = TRUE)
d[file.access(df, 0) == 0] # all exist
d[file.access(df, 1) == 0] # some are executable, some are not
d[file.access(df, 2) == 0] # hopefully all are readable
d[file.access(df, 4) == 0] # they may or may not be writable
I presume mode = 2 is a test for writing, so could someone change the comments
around in the Examples
