win2k memory problem with merge()'ing repeatedly (long email)
Good afternoon, I have a 63 small .csv files which I process daily, and until two weeks ago they processed just fine and only took a matter of moments and had non noticeable memory problem. Two weeks ago they have reached 318 lines and my script "broke". There are some missing-values in some of the files. I have tried hard many times over the last two weeks to create a

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?

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

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

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 with about 4GB of memory, and R 2.5.0. upon startup, gc() reports used (Mb) gc trigger (Mb) max used (Mb) Ncells 268755 14.4 407500 21.8 350000 18.7 Vcells 139137 1.1 786432 6.0 444750 3.4 This is my baseline. linux

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. I do have another 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. ## Create Sample File

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

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! Lucky

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,

use of setsockopt(SO_LINGER)
I would like to remove setsockopt(SO_LINGER), as there does not seem to be a reason for its use. If you know of specific reasons we should keep any of these let me know, or run this patch in local test trees where possible. This is against OpenBSD, but should apply to portable with some fuzz.
