Native implementation of rowMedians()
Hi,
I've got a version of rowMedians(x, na.rm=FALSE) for matrices that
handles missing values implemented in C. It has been optimized for
memory and speed. To avoid coercing integers to doubles, and hence
allocate an additional 200% memory, there is one C function for
integers and one for doubles.
The rowMedians() implementation is currently sitting in my non-CRAN

R CMD check --as-cran and (a)spell checking
Does anyone know if it is possible to add a dictionary file of known
words that becomes part of the *built* package to tell 'R CMD check
--as-cran' not to report these words as misspelled. I want this
dictionary to come with the *.tar.gz such that it will be available
regardless where the package is checked. For instance, currently I

Minor bug in maketitle.pl (with bug correction) (PR#864)
Full_Name: Henrik Bengtsson
Version: rw1022
OS: Windows Me
Submission from: (NULL) (216.175.126.55)
When ${R_HOME}/share/perl/maketitle.pl tries to generate a TITLE that is longer
than $lc-3 (=13) characters long, it repeats the package name on line two.
Example: Now it generates an output like:
com.braju.graphics

Title of bundled packages in the library index (PR#1017)
Full_Name: Henrik Bengtsson
Version: 1.3.0
OS: Windows Me
Submission from: (NULL) (216.175.122.171)
I realized that the title of packages in the library index when they are in a
bundle is the title of the bundle and not the package.
It looks like the TITLE file, which apparently is used for generating the
library index, takes the value of the bundle's title and not the package's
title.

Depends, require(), autoload() and "side effects"?
Hi.
If your package require another package in order to define its methods (but
afterwards in is not needed), how should one specify this? Is it correct to
assume that "Depends" will assure that all packages are loaded (attached?
what is the right word) *before* the methods in the current package are
defined? Basically I use my own setMethod() called setMethodS3() that is
defined in

scan without line numbers?
When using the function scan(quiet=TRUE) the line numbers are printed.
Example:
> scan(quiet=TRUE)
1: 123 [ENTER]
2: [ENTER]
[1] 123

Is it possible to not show the line numbers? I know about readLines() but I
would like to be able to use the extra features of scan().
Thanks for you help!

ASCII map?
Is there a way to convert between and integer and a character and vice
versa? For instance
i <- 65;
ch <- intToChar(i); # "A"
i <- charToInt(ch); # 65
or even better
i <- c(65, 66);
ch <- intToChar(i); # c("A", "B")
i <- charToInt(ch); # c(65, 66)
I have tried to do a ASCII map myself, and I figured out that the ASCII

easier way to update packages i'm developing?
I'm frightfully new at developing r packages. I'm developing an econometrics
package, and each time I update my beta package, I close R, delete the
package dir in the library dir, rebuild the zip file, rerun R, reinstall the
package and run the functions. Is there a more efficient way?
Jeff.

Cleaning things up?
Hi,
I know it must be written somewhere but I can't find it.
I'd like to remove all variables or objects that I've created but not the
functions. I look at a few things without success. Is there a R way of doing
this? There are to many to create a manual list.
Thanks in advance.

str() with attr(*, "names") is extremely slow for long vectors
Hi,
I noticed some time ago that, for instance, named vectors that are
really makes str() really slow when displaying the names attribute. I
don't know exactly when this started, but it wasn't the case say 1-2
years ago. Example (on a WinXP 1.8GHz):

> system.time(str(s))
Named int [1:1000] 1 2 3 4 5 6 7 8 9 10 ...

I tried running Rcmd.exe to no avail. It doesn't even start because it tries
to read some memory address that NT says it can't and terminate.
I tried downloading and reinstalling rw1020sp.zip with the installer twice

same problem.

How to get the penalized log likelihood from smooth.spline()?

right thing) I clarify my problem trying to use the same notation as in
