call step inside a function
I am wondering why my function works fine in R1.7.1 and R1.8.1 but not in
R1.9.0. I thought it's an environment related problem but I can't solve it.

Memory R and Windows2000
Hello,
when using: rm(list=ls(all=TRUE)) and gc() command , and looking at the
memory
used by Rgui.exe in window2000 there is no change.
this is strange .
Actually I need to be sure that memory is given back to the system
because the users of the application I wrote under R are opening and closing
big files of data;
can I rely on the gc() function under win2k?

Converting from char to POSIX:

Sorting a dataframe
Undoubtedly a simple question:
I've looked at order() and sort() in the help pages for
R1.7.1. It doesn't appear that these functions are immediately
suited to doing the same thing as
PROC SORT DATA = BLAH;
BY X Y Z;
RUN;
in SAS. I have also checked Frank Harrell's Hmisc library.
Could someone point me in the right direction so I can sort
by the levels of Z within the levels of

data.frame to matrix
Hello all,
I've had trouble converting a data.frame to a matrix (numeric) using either
data.matrix() and as.matrix().
After executing one of those I end up with another data.frame with only the
first column of the original data.frame.
I use a window (tcltk) to let the user choose the columns he wants and then
I retrieve them using the following:

sys.on.exit not working (PR#7665)
Full_Name: Mark Bravington
Version: 2.0.1
OS: Windows XP
Submission from: (NULL) (140.79.22.104)
'sys.on.exit()' doesn't seem to be working, since R1.7.1 at least:
soe.test <- function() {
on.exit( cat( 'In exit code\n'))
str( sys.on.exit()) # should display "language..." I think

}
(A similar bug was apparently fixed for version 0.65!)

System slow down (PR#3668)

Version: 1.7.1
OS: XP Home Edition
Submission from: (NULL) (131.202.163.72)
Recently have been using R1.7.1 on a new laptop computer. System and software
worked fine for at least two weeks. Now the entire OS slows down to the point
where one would think it had frozen. I feel there must be a compatibility issue
between R and XP Home (including auto updates / service

Matrix Multiplication
R1.7.1/Win2k:
Apologies if this posts twice - the first message
was not in plain text.
I have looked in help.start() and tried typing
"crossprod" and "%*%" into the RGui to get an idea
for what R is using as internal algorithms for
its matrix computations/manipulations... to no
avail.
Could someone point me in the direction of some
documentation? All I get for

reading a 40kb csv file in R
I am trying to read a matrix of 5000*2000 from a csv
file of real numbers in R using the scan function. I
am getting an error saying that R can not read a
vector > 32KB and it can't allocate a memory of 191 MB
etc.
What should I do. I am using R1.7.1.

Hello,
I'd like to catch the warnings in a variable in order to evaluate them, but...

Warning messages:

Problems loading dataset in Rcmdr
Hello all!
I?ve been using Rcmdr for some time, as a quick way of producing
graphics and basic statistics. I run R1.8.1, OS W2000.
Two days ago the dataset loader stopped working. Normally, the button
<No active dataset> is clickable to give you the opportunity to choose
dataset to load in the Rcmdr context. Clicking on the button now
produces this:

unexpected behavior in plot
I'm having difficulty getting plot to work with type="n", when either the x or y variables is a factor.
For example,
x <- 1:10
y <- 1:10
plot(x, as.factor(y), type="n")
plot(as.factor(x),y, type="n")
plot(y ~ as.factor(x), type="n")
produce plots with data plotted, whereas
plot(x,y, type="n")
plot(y ~ x, type = "n")
