coplot panels malrendered / 1653 (PR#2824)

This was previously reported I believe as bug 1653.
I just compiled 1.7.0 on RedHat Linux and I get terrible behavior when
panel=plot. Browsing through the coplot code, I don't how there could be this
dependency. With panel=points, my 7 graphs come out numbered as

segfault with layout() after closing X11() device (PR#8970)
Full_Name: Don Maszle
Version: 2.3.0
OS: Solaris 9 - 64 bit compile
Submission from: (NULL) (206.86.87.3)
After closing an X11() window by either clicking on the close button
or by calling dev.off(), R 2.3.0 segfaults as shown below. Calling layout()
before any X11() device is opened just opens a new device and applies the
layout.

I am getting "Error: cannot allocate vector of size 197 MB".
I know that similar problems were discussed a lot already, but I
didn't find any satisfactory answers so far!

appeared I had 1.5GB of available physical memory.

growing process size in simulation
I came across this in a simulation I ran under 1.6.0: If I do something
like
R> x <- rnorm(10)
R> rval <- NULL
R> for(i in 1:100000) rval <- t.test(x)$p.value
then the process size remains at about 14M under 1.5.1, but it seems to
be almost linearly growing up to more than 100M under 1.6.0.
I know that the above simulation is nonsense, but it was the simplest I
could come up

Memory Experimentation: Rule of Thumb = 10-15 Times the Memory
dear R experts:
I am of course no R experts, but use it regularly. I thought I would
share some experimentation with memory use. I run a linux machine

Memory Experimentation: Rule of Thumb = 10-15 Times the Memory
Hi,
I've been having similar experiences and haven't been able to
substantially improve the efficiency using the guidance in the I/O
Manual.
Could anyone advise on how to improve the following scan()? It is not
based on my real file, please assume that I do need to read in
characters, and can't do any pre-processing of the file, etc.

Memory issues in R
How do people deal with R and memory issues?
I have tried using gc() to see how much memory is used at each step.
Scanned Crawley R-Book and all other R books I have available and the FAQ
on-line but no help really found.
Running WinXP Pro (32 bit) with 4 GB RAM.
One SATA drive pair is in RAID 0 configuration with 10000 MB allocated as
virtual memory.

Large discrepancies in the same object being saved to .RData
Hi developers,
After some investigation I have found there can be large discrepancies in the same object being saved as an external "xx.RData" file. The immediate repercussion of this is the possible increased size of your .RData workspace for no apparent reason.
The function and its three scenarios below highlight these discrepancies. Note that the object being returned is exactly

LCG with modulo 2^30
I can't run a function which generates random numbrers using linear
congruential generator. My multiplier is a=5+8^6, increment is b=1 and
modulo is m=2^30.
the code I have written works for modulo upto m=2^28.
For m= 2^29 , it says, can not allocate memory for the vector or something
like that.
For m= 2^31 or more, its says the argument "for i in 1:m " is too large in

win2k memory problem with merge()'ing repeatedly (long email)

R not giving memory back to system?
This might be because I didn't get it right, but; I thought R would
release memory back to the system as (big) objects get removed?

overhead of function calls
Hi,
Profiling shows that 65-70% of the time of my program is spent inside
a single function -- this is not surprising, as it is inside an
optimize call inside a loop (this is a dynamic programming problem).
I would like to speed this up.
The function does very little: has a single argument, evaluates a
spline at that argument, does some simple arithmetic with it (adding
constants,

R.oo Destructors
Has anyone figured out how to create a destructor in R.oo?
How I'd like to use it: I have an object which opens a connection thru RODBC
(held as a private member) It would be nice if the connection closes automatically
(inside the destructor) when an object gets gc()'ed.
Thanks in advance.
Regards,
Ken
BTW, a >BIG< thanks to Henrik Bengtsson for creating the R.oo package!
