capturing output from Win 98 shell
How can I best achieve the following (works in Splus):
filenames <- dos("dir *.sasb7dat /b")
What I am asking, more generically, is: how can I capture the output of
a
DOS command in R?
I have tried using
system("COMMAND.COM /c dir /b", intern=T, show.output.on.console=T)
where
intern: a logical, indicates whether to make the output of the

Problem with data.frames
Hi,
I just encountered a problem in R that may easily be fixed: If one uses
attach for a data.frame e.g. 10000 times and forgets detach, then R gets
incredibly slow (less then 10% of the original speed).
My system:
platform powerpc-apple-darwin6.0
arch powerpc
os darwin6.0
system powerpc, darwin6.0

ISOdate returns incorrect date?
Dear all,
I have found the following (for me) incomprehensible behaviour of
ISOdate (POSIXct):
> ISOdate(1900,6,16)
[1] "1900-06-15 14:00:00 Westeurop?ische Sommerzeit"
> ISOdate(1950,6,16)
[1] "1950-06-16 14:00:00 Westeurop?ische Sommerzeit"
Note that in the first case I get the 15th of June back, not the 16th as
I would have expected!

excel files and R
Greetings everyone,
I am new at R. My questions is rather basic. Looking R manuals looks
like there should be a way to read MS excel files into R. Could
somebody tell me which library should I use for that?
Thanks in advance

address for bug reports? (PR#5171)
bug.report() tells me to email to r-bugs@r-project.org, whereas

Which should I believe?

I've forgotten, why is box("") the default?
I've searched on CRAN for axes, axis, and other terms
I've already forgotten, without (re)discovering the
reason for S using "non-joining" axes by default, instead
of box("l").
MASS points me towards Cleveland (1993) but I don't
have ready access to this any more. Could someone
give me a one-liner to justify this choice to a sceptic?
It's something to do

I want to share my joy with you. Please see the following
excellent introduction to R "Statistiques avec R " by

In paticular, you can see a lot of fascinating graphics
examples of R from which you can get many hints.

Numbers that look equal, should be equal, but if() doesn'tsee as equal (repost with code included)
Try the following function (the name is supposed to be a joke, by the
way),
which will also do the right thing with NAs and characters. Use it as
if(equal.enough(x,y)) rather than if(x==y), e.g.
> equal.enough(0.1+0.2, 0.3)
[1] TRUE
My default of 15 significant figures may be overkill in many
applications; be
prepared to reduce this.

Weird problem with median on a factor
Hi all,
I hope this isn't a naive newbie question again. Here you can see column 264 of

264 contains the answers of 49 persons to a question in May.

grep and gsub on backslash and quotes
The following code works, to gsub single quotes to double quotes:
line <- gsub("'", '"', line)
(that's a single quote within doubles then a double within singles if
your
viewer's font is not good).
But The R Language Manual tells me that
Quotes and other special characters within strings
are specified using escape sequences:

seeking help with with()
I tried to define a function like:
fnx <- function(x, by.vars=Month)
print(by(x, by.vars, summary))
But this doesn't work (does not find x$Month; unlike other functions,
such as
subset(), the INDICES argument to "by" does not look for variables in
dataset
x. Is fully documented, but I forget every time). So I tried using
"with":
fnxx <- function(x, by.vars=Month)

source problem
Hi,
I'm trying to call an R script from the command-line ("firstScript.r"
below). This script then sources another script in another directory
using the absolute path to the file
("/home/john/R_script/secondScript.r"). That script then needs to
source an R script in the same directory using a relative path
("thirdScript.r"). Neither script should know that it

Plotting a function with curve()
Why does
> curve(function(y) y^2, from=0,to=1)
not work, whereas
> myf <- function(y) y^2
> curve(myf, from=0,to=1)
work?
For the former, I get the error message
Error in curve(function(y) y^2, from = 0, to = 1) :
'expr' must be a function or an expression containing 'x'

R and pointer
Hi everyone,
I want to write a function that modify directly variables passed as
parameters (the equivalent in C language of *ptr/&ptr) so that I don't
have to return a list and to reaffect all my variables.
Is it possible to do so in R?
Thanks a lot.
