Hi, I noticed the temperature of my laptop rises sharply during execution of a long R script that generates several hundred plots, all of them saved to files. No screen output. Temps reached above 90 Celsius degrees in the box and above 80 C deg in the processor. The machine turns on cooler at maximum speed and exhaled air is really hot. Tried similar operations (batch graphic and music

A possible regex bug when working with large strings. The following code snippet t5 <- paste( c( "# === TEST", rep(' ', 2452294) ), collapse='') str( sub("^.*TEST", "xyz", t5) ) str( sub("^.*TEST", "xyz", substr(t5,0,200)) ) doesn't behave right; on one machine, the second and third lines print different results [the

Hi, I'm running a simple test from asterisk towards a public telco switch (AXE10) over E100P. Here is the test case: 1) 30 calls are setup simultainously, 20 sec ringing time. 2) no calls answers (just calling a vacant public tax office :=) 3) Each channel will continue on its own with the same proceedure: ring for 20 sec, then hangup, ring for 20 sec, and so on. Of course this leads to

The deadline for student applications is 19:00 UTC on Friday 6th April: http://www.google-melange.com/gsoc/events/google/gsoc2012 That's just over 36 hours away as I write this. The deadline is sharply enforced by the melange software, and you won't get an extension, so don't leave it until the last few seconds, as you might have an unexpected internet outage. There's also no

Hello, I am using the R randomForest package to classify variable stars. I have a training set of 1755 stars described by (too) many variables. Some of these variables are highly correlated. I believe that I understand how randomForest works and how the variable importance are evaluated (through variable permutations). Here are my questions. 1) variable importance error? Is there any ways

Dear ALL, IHAC who would like to use Sun Fire X4500 to be the NFS server for the backend services, and would like to see the potential performance gain comparing to their existing systems. However the outputs of the I/O stress test with iozone show the mixed results as follows: * The read performance sharply degrades (almost down to 1/20, i.e from 2,000,000 down to 100,000) when the

Hi. In this setup "account has_many :consultations". Can anyone explain the following behaviour to me? Rails 1.2.2. The "sum" method should return 0 for an empty array. >> a = Account.find(1) => #<Account:0x39c80a8 @attributes={...} >> a.consultations => [] >> a.consultations.sum(&:foo) ArgumentError: wrong number of arguments (1 for 2)

Yes, you are right. During my testings, I tried the llvm produced .S files with the gcc frontend and it compiled and linked them to the final executable. The problem is with the gcc and binutils licence. This is GPL and while this is ok for open source or for academic purposes, it can't be used on commercial projects. In fact one of the strong points of llvm (and clang) is its BSD like

Hello, From a user perspective, the simple (tcpri) and complex TC configs offers two rather distinct choices. A user can very well be OK with only using the simple way and that''s very fine. Then again, even in doing so, the more complex config options are available. What is the interplay between the two as far as having some parameters configured in both at the same time ? So far

Hi Chandler, Thank you very much for sharing this! The RFC is pretty lengthy but the far majority of it makes sense to me. I’m sure I’m forgetting to react to some aspects below, but I thought I’d summarize some initial thoughts and questions I had after reading the RFC end-to-end. * I believe the same high-level principles you outline can also be used to implement the same protection on the

Hola! I have a problem which is not strictly R, although R will be used for the analysis. We have data from a large investigation of drug abuse, initially analyzed by logistic regression. But the pupils are selected by first sampling schools, and as it happens the prevalence of use varies sharply from school to school, so there is over-dispersion. Now we are interested in comparing the

Dear r-helpers, I know that there has already been enough questions on IO performance these last days, but I came accross the following situation today. I was comparing the performance of R with that of SAS's Risk Dimensions at generating random "scenarios". My dataset --all numeric entries-- would nicely fit into RAM and R would outperform SAS until... I wanted to export the

Hi, I am facing a problem in extrapolation of data series. It is a series of Bond yields, I am having the yield for 1 year to 30 years. I want to find the yield for 0.5 year and 30.5 years. I used the Langrange's Extrapolation but the extrapolation deviates from the normal trend ( as we can see in theoritical yield curves) very sharply, as go on increasing my years from 30 years to 35 years

Dear R list, I've read the function writing sections on both "An introduction to R" and "R language Definition" manuals but still don't understand why the following gives an error message: fun <- function(x, ...) x + y fun(1, y=2) I get: Error in fun(1, y = 2) : object "y" not found I'd appreciate any help in understanding this. R version 2.4.1

Hi all, I'm currently using the 'rpart' function to run some regression analysis and I am at the point where I wish to prune my overfitted trees. Having read the documentation I understand that to do this requires the use of the complexity parameter. My question is how to go about choosing the correct complexity parameter for my tree?
