scan() crash in Windows 98 (PR#3234)

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 command an R

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 status major 1 minor 6.1 year 2002

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! This happened under R-1.7.1 on

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 Victor H.

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

"Statistiques avec R"
Dear R users, I want to share my joy with you. Please see the following excellent introduction to R "Statistiques avec R " by Vincent Zoonekynd http://zoonek2.free.fr/UNIX/48_R/all.html In paticular, you can see a lot of fascinating graphics examples of R from which you can get many hints. Soryy if this is already well-known, but the CRAN search did not show nothing with the keyword

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.

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: \' single quote \"

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

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. Laetitia Marisa.
