hello
Hello,
I am a new user.
I would like to know if it is possible with R to fix the position of
ticks.
for example for my plot I obtained automatically the positions
200,400,600,800 and 1000 on x axis and so a scale of 200
But I would like to obtain
100,200,300,400,500,600,700,800,900,100 so a scale of 100.
Which fonction can help me to do so?
thank you

normality test
Hello
I have used recently the kolmogorov smirnov test,
which is a test of normality.
This test is named ks.test() in ctest library of R.
I wonder if the results of ks.test () are true, because
the results are strange, time to time.
thank you for help

hello,
can some body help me to get
the residuals and the variance of coefficient after an autoregressive
fit.
These values are present in the ar function of the package ts.
But I don't know how to makes it work.

Memory management
Dear all,
I don't get it:
First of all, the help doesn't say what are the memory limits of
R. Say, what's the max heap size for instance ????
Secondly, I invoke R with the following commands each time:
rgui --vsize 30M --nsize 1000K
rgui --vsize 30M --nsize 2000K
rgui --vsize 30M --nsize 3000K
rgui --vsize 30M --nsize 4000K

Hello,
Splus contains the function intbin(x,l).
This function allows to make a conversion from an integer x to a binary of
length l.
for example
intbin(3,2) returns 11
intbin(3,3) returns 011
Do you know how to do it in R ?
Thank you meriema

How do you expand memory capability (Was: R crashes in Windows ME)
Hello-
Since my data bank in SPSS has > 40 variables, I think that R crashes because of the memory limit.
In Maindonald?s UsingR text, on pg 3, there?s a footnote that reads:
"If you want larger memory space than the default you may want a target akin to
<path to binary>\rw091\bin\rgui.exe --visize 30M --nsize 1000K
[The default is --vsize 6M --nsize 250K

heap size trouble
Hi ,
I ''ve got a trouble with using R.
When I want to load a file that contains 93 thousand raws and 22 colums
of data (essentially float)
R shows me this error message
"heap size trouble"
Does anyone could tell me what parameter shall I precise before
launching R in order to load my big file.
Thanks a lot

Heap size
Hi,
I am trying to create a matrix 8000x8000 but cannot
make R work properly with:
rgui --vsize 30 --nsize 1000000
I can't pass an nsize value more than 1000000.
What are the limits uder windows 98 ?
Best,

R-0.65.1 Startup
Dear R users,
I have noticed that my R startup is extremely slow. It takes almost 3
minutes from "double-click" to R prompt. I have been running R-0.64.1 till
recently and it took about 30 sec. I still have access to R-0.64.1. When I
started it up, it took about 25 sec. Can anyone tell me if this is a bug in
R or a problem with my machine?

maximum of nsize=20000k ??
Dear R-ers,
somehow it is not possible to increase nsize to more than
20000k. When I specify e.g.
> R --vsize=10M --nsize=21000K
the result is:
free total (Mb)
Ncells 99658 350000 6.7
Vcells 1219173 1310720 10.0
Maybe I have overlooked s.th....

function pointers?
We have a project that calls for the creation of a list of many
distribution objects. Distributions can be of various types, with
various parameters, but we ran into some problems. I started testing
on a simple list of rnorm-based objects.
I was a little surprised at the RAM storage requirements, here's an example:
N <- 10000
closureList <- vector("list", N)

tree problem
I am trying to use tree to partition a data set. The data set has 3924
observations. Partitioning seems to work for small subsets of the data,
but when I use the entire data set, no partitioning occurs. The
variables are:
RESP respondent to a survey (0 = not a respondent, 1 =
respondent)
AGE_P Age (continuous)
ORIGIN_I Hispanic Ethnicity (1 = Hispanic, 2 = non-Hispanic)

vsize and nsize
I am running R version ??? under Redhat 5.2. It seems as though the
--nsize object has no effct on the size of the allocated Ncells as
determined using gc(). Yes, I have that much data....
That is if I envoke R with
R --vsize 100 --nsize 5000000
then type
gc()
I get
free total
Ncells 92202 200000
Vcells 12928414 13107200
