similar to: Converting monthly data to quarterly data

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 problem with the library fCalendar. I am not using the US standard format notations. It seems like it is not possible to have different format than the US standards. Anyone how knows a way to go around this problem? Here is the code I enter: myDate = "12.03.2005" timeDate(myDate, format = "%d.%m.%Y") And I get following error message: Error in if

Hi folks, Suppose I create the character vector charvec by > charvec<-c("a1.b1","a2.b2") > charvec [1] "a1.b1" "a2.b2" and then I use strsplit on charvec as follows: > splitlist<-strsplit(charvec,split=".",fixed=TRUE) > splitlist [[1]] [1] "a1" "b1" [[2]] [1] "a2" "b2" I was wondering

Hello, Sorry if anyone gets this message twice, as my mailserver may not be working. Thanks for your response. Your idea makes a lot of sense to me, but I've been unable to get seconds to work. I ended up with this format finally: "2007-10-31_16:20:22" Problem is I am unable to get it recognized as a date using timeDate(): R>

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

I wasn't even aware I was using midnightStandard. You won't find it in my script. Here is the relevant loop: date1 = timeDate(charvec = Sys.Date(), format = "%Y-%m-%d") date1 dow = 3; for (i in 1:length(V4) ) { x = read.csv(as.character(V4[[i]]), header = FALSE, na.strings=""); y = x[,1]; year = V2[[i]]; week = V3[[i]]; dtstr =

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;

Hi folks. This set of code used to work, but after upgrading to the latest version of Rmetrics it no longer does. Any ideas?

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.

Hello, I have a data set has 2001Q1 100 2001Q2 101 2001Q3 120 2001Q4 103 ... And would like to convert it to a monthly data. i.e. 200101 XXX 200102 XXX 200103 XXX

For a model I am working on, I have samples organized by year and week of the year. For this model, the data (year and week) comes from the basic sample data, but I require a value representing the amount of time since the sample was taken (actually, for the purpose of the model, it is sufficient to use the number of weeks from the middle of the sample week to the present). What I have found so

Hi, Can someone explain the proper use of the use of perform_deliveries in the environment.rb file?? ActionMailer::Base.perform_deliveries = false I just moved a new controller to the production version of an app, but wanted to be sure everything was properly configured before sending out a big mailing, so I set perform_deliveries = false, believing that would prevent mail from being

Hi, I am new to use R, but can anyone tell me how to tranform quarterly data to monthly data? I know SAS has this procedure, so may I assume it is also available in R? Thanks a lot! Ed

Hi, I''m looking at ways to encrypt email addresses rather than storing them directly in the database. There are several ways that it could be done. I could make an Encrypter class and use before_update, etc. Or I could set up an updatable VIEW in mySql. (I guess triggers might be another possibility.) However, what I would really LIKE to do is use the handy AES_ENCRYPT and

Hi guys, I am logging data about my body (weight, body fat, blood pressure, ..) in a .csv file and would like to plot this as a time series.
