Hi, I have a couple of aggregation operations that I don't know how to accomplish. Let me give an example. I have the following irregular time series time x 10:00:00.021 20 10:00:00.224 20 10:00:01.002 19 10:00:02:948 20 1) For each entry time, I'd like to get sum of x for the next 2 seconds

Hello R-universe... I am having trouble writing a function which contains a loop so I can sapply() it to a list of data frames Each data frame has 241 observations of 15 variables. My loop takes a random sample of one row until the 40 consecutive rows after the sample have a d2p(variable) sum greater than 5. here is my loop code (it works fine when applied to a 241 observation data frame):

Dear all, I have data like 3 coulmns and many rows. Each entry is less than 10. Example x y z 1 5 3 2 2 3 7 8 3 8 9 5 4 5 4 6 -------------------------- --------------------------- I have to sum entries of each coulmn (seperately) till it be 10. This i have to start for each row. And I want to assign no. of rows needed including that row too(it to be 10 or 10+, the moment it exceeds 10, i

I'm trying to get SNMPv3 management working for an APC AP9617 card. It is newly refurbed, running sumx v3.7.2 and aos v3.7.3. In the SNMPv3 user profiles section I have (I don't care about the password leaking, it's temporary): User Name: nut Authentication Passphrase: NutScan at Password43LongerWord Privacy Passphrase: NutScan at Password43LongerWord Authentication protocol:

Hi, Again, sorry for the length of this post. Once I get my new office I will get a website set up on my work machine and will simply post a link to the log since I doubt many people are truly interested in these logs. To further analyze what is happening, I added my own routine in main.c called DEBUG_SET_NAMED and then redefined the SET_NAMED macro to use it and then rebuilt R. I

In their paper, "Lexical Scope and Statistical Computing", the authors ( Gentleman and Ihaka ) go to great length explaining why R's use of lexical scoping creates advantages when doing statistical computations. If anyone has or is familiar with this paper, could they provide the main program code for how the "newton" function would be called in their example on page 500

Full_Name: Ed Borasky Version: 1.8.1 OS: Windows XP Professional Submission from: (NULL) (208.252.96.195) R 1.8.1 seems to be running into a memory allocation problem in the "aggregate" function. I have a rather large dataset (14 columns by 223,000 rows -- almost 40 megabytes) and a script that performs some processing on it. The system is a 768 MB Pentium 4. Here's the console

Hi, I am new in R and have some frustrations as how to set debug breaks during emacs R debug. I use debug () as where or which function to debug. But during the debug, e.g., I have a for loop at the beginning of the function code and want the code execution to jump through that for loop and set a break after that. How to do that? Is there a web site detailing the syntax of the debugging of R?

Dear all, I have written a little R program to convert images. See below. Within the loop over j (the filenames) memory consumption grows constantly. rm( ... ) inside the loop did not help. Memory does not grow if I remove the writeBin statements between the two #-------- marks. But obviously this is not solution I want... Thanks for any advice. Manfred Baumstark P.S. As I'm new to R:

[some de-capitalization of *SXP done manually by mailing list maintainer ; the originally was caught as potential spam. MM] I have a little R program that crashes with the message xmalloc: out of virtual memory The code has a repeat{} loop that watches the sizes of some files. When there's an increase it updates things by reading the last 65 lines of each file, doing some

I'm confused by this: > identical(function() {}, function() {}) [1] FALSE Yet, after loading the Matrix package (which redefines det), the following is checked (in library.checkConflicts): > identical(get("det", baseenv()), get("det", asNamespace("Matrix")), ignore.environment=T) [1] TRUE I've looked at the code in identical.c and for closures it

Specifically, the srcfile attribute of the srcref attribute of the two instances of the functions contain different environments, AFAICT. Environments are compared only by exact pointer, so this forces return FALSE.

Hi, everyone. I'm trying to debug an R-module, written in C, and I'm using gdb for this. How can I print "standard" R objects from within C code? BTW, I'm familiar with the advice to use R_PV given in Writing R Extensions, but it's not working for me. E.g., I get (gdb) p R_PV(x) $1 = void and yet (gdb) p *x $2 = {sxpinfo = {type = 16, obj = 0, named = 0, gp = 0,

Happy new year to all; A few days ago, I posted similar problem. At that time, I found out that our R program had been 32-bit compiled, not 64-bit compiled. So the R program has been re-installed in 64-bit and run the same job, reading in 150 Affymetrix U133A v2 CEL files and perform dChip processing. However, the memory problem happened again. Since the amount of physical memory is 64GB, I think

Hi, all; I know there has been a lot of discussions on memory usage in R. However, I have some odd situation here. Basically, I have a rare opportunity to run R in a system with 64GB memory without any limit on memory usage for any person or process. However, I encountered the memory problem error message like this: Error: cannot allocate vector of size 594075 Kb I got this error message while

I'm running nut-2.8.0-3.el8.x86_64 on CentOS Stream 8 talking with an APC Smart-UPS RT 5000 RM XL via a Network Management Card AP9619 (version A10). Up to today I would receive occasional COMMBAD messages, then 5 minutes later I'd see a COMMOK.Maybe 1 or two a day. Today I updated the firmware on the AP9619 from 3.7.2 to SUMX 3.9.3 and AOX 3.9.4, the most recent releases available for

I have three APC SmartUPS 5000s. Two of them are AP9617 and one is AP9619. I have a RS-232 connections from my monitor host to all three. All three report status and give information. One of the two AP9617 - ups3-1 - does not shut down when FSD is sent. It did when I first set this system up a year or two ago but it's stopped doing so since then. Resetting the management interface does not

Just a hunch about your snmpwalk, what happens if you format like this? snmpwalk -l authpriv -v 3 -u user -a MD5 -x DES -A authpassphrase -X privpassphrase {host address} so snmpwalk -l authpriv -v 3 -u nut -a MD5 -x DES -A NutScan at Password43LongerWord -X NutScan at Password43LongerWord apcups Thank you, David Zomaya Tripp Lite ________________________________ From: Nut-upsuser

I have a general question about coefficients estimation of the mixed model. I simulated a very basic model: Y|b=X*\beta+Z*b +\sigma^2* diag(ni); b follows N(0,\psi) #i.e. bivariate normal where b is the latent variable, Z and X are ni*2 design matrices, sigma is the error variance, Y are longitudinal data, i.e. there are ni

I am grateful for the advice of Douglas Bates on my earlier problem in making R-0.62.1, but I'm afraid I'm still having problems.... I have been installing the various updates to R for quite some time on my alpha, and it is only now that I have been having really severe problems. The three or 4 versions before 0.61.1 installed without error. For 0.61.1 I needed to install GNU make. For
