Dear Gavin, This is really great, thank you! I created some long loops to get rid of extra months at the beginning and the end of my data but your code is great for putting it then together quarterly. thanks again, Denise On Mon, 2008-08-18 at 14:31 +0100, Denise Xifara wrote: > Thank you very much Stephen, but how will aggregate deal with months that > fall outside annual quarters? eg,

Dear R users, I have a dataframe where column is has countries, column 2 is dates (monthly) for each countrly, the next 10 columns are my factors where I have measurements for each country and for each date. I have attached a sample of the data in csv format with the data for 3 countries. I would like to convert my monthly data into quarterly data, finding the mean over 3 month periods for

Dear All and Mark, Given a dataset that I have called dat, I was hoping to speed up the following loop: for(i in 1:835353){ for(j in 1:86){ if (is.na(dat[i,j])==TRUE){dat[i,j]<-0 }}} Actually I am also having a memory problem. I get the following: Error: cannot allocate vector of size 3.2 Mb In addition: Warning messages: 1: In dat[i, j] <- 0 : Reached total allocation of 1535Mb: see

Hi all, I am trying to call a C function from R (version 2.10.1) on a windows machine. The C code is in a .c file, I have pasted the code below although I'm very confident that it does not contain any errors (it is not my code), but also, the problem that I have occurs with every .c file that I have tried this with. I have installed Rtools and included: C:\Rtools\bin; C:\Rtools\perl;

Dear R users, My question is about finding the proper font size for graphics. For this i had written a code that creats 4 diferent graphics and saves them as a png file. >From these PNG.graphics , i select one of the proper size and past it to a word document. I have experimented with lots of settings yet:nd lost my track a bit. there are cex; cexaxis cexlabes and so on, i lost track of

This patch introduces an optimized assembler version of md5_process(), the inner loop of MD5 checksumming. It affects the performance of all MD5 operations in rsync - including block matching and whole-file checksums. Performance gain is 5-10% depending on the specific CPU. Originally created by Marc Bevand and placed in the public domain, later integrated into OpenSSL. This is the original

Running dovecot 1.2.12 on ubuntu 10.10. Here is the problem: I have mysql backend for expire.

Hi, This appears to be some sort of dovecot bug. When I use the -r option to recursively delete a mailbox and sub-folders, it removes the sub-folders but not the inbox. It gives me the error below: doveadm mailbox delete -u denise at lifelinetechnique.com.au -r -s inbox doveadm(denise at lifelinetechnique.com.au): Error: Can't delete mailbox inbox: INBOX can't be deleted.

Hi, I was looking around the LLVM instruction set and I failed to find ROL and ROR instructions. Is there any plans on adding these instructions to LLVM? The reason that I am asking is for cryptographical algorithms which are becoming ever more important rotation is a major operation. Thus including such instruction could reduce 3 instructions {shl, shr, or} into {rol | ror} which could gain

Hi R Helpers, I recently tried to take advantage of the ability to download all the tickers in the S&P 500 using the functionality of tidyquant, but it threw an error. For summary, the set of commands that I ran was library(tidyquant) tq_index_options() tq_index("SP500") sessionInfo() R feedback including error message and sessionInfo are provided below. Guidance would be

I have hundreds of megabytes of price data time series, and perl scripts that extract it to tab delimited files (I have C++ programs that must analyse this data too, so I get Perl to extract it rather than have multiple connections to the DB). I can read the data into an R object without any problems. thedata = read.csv("K:\\Work\\SignalTest\\BP.csv", sep = "\t", header =
