Hi, Given a date, how do I get the last date of that month? I have data in the form YYYYMM, that I've read as a date using > x$Date <- as.Date(ISOdate(substr(x$YearEnd,1,4),substr(x$YearEnd,5,6),1)) But this gives the first day of the month. To get the last day of the month, I tried > as.Date(as.yearmon(x$Date,frac=0)) But I don't get the last day of the month here. (Tried

Dear R experts, I have a dataframe imported from a csv file (with read.csv). Here is an example: yyyymm<- c("19860228", "19860331","19860430","19860531") id<-c("10000","10000","10000","10000") re<- c("C","0.25", "0.98", "1.34") mret<-data.frame(yyyymm, id, re)

I need to merge three datasets and don't know how. If I were using SQL, I would use df3, look up the characteristics of each date in df1 and the value for each observation in df2. df1 - unique list of Dates and characteristics of those dates Date, YYYYMM, YYYYWW, DOW df2 - the raw data Date, Place, Value df3 - all posibile combinations of Date + Place (via

I have a vector that contains month and year in the format YYYYMM (e.g.“200701”, “200702”) I wish to do to things: 1. I need to convert to a date that is the last calendar day of each month. 2. I need to convert this to a date that is the last U.S. stock-exchange trading day of each month. Any advice is appreciated, mymonths <- c(200701, 200702)

Hi, I am trying to create a googleVis motion chart with monthly data. When formatting the date column as a Date class variable, the plot as presented in the browser becomes considerably slower and very prone to crashing the browser. To illustrate this issue I have modified the WorldBank demo. ### objects from demo("WorldBank", package = "googleVis") M <-

Dear anyone who knows more about R than me (so everyone). I have been bashing my head on the keyboard all day trying to do something with my table. I have some data, like so: yyyy-mm Rainfall(mm) 1 1977-02 17.4 2 1977-03 34.0 3 1977-04 26.2 4 1977-05 42.6 5 1977-06 58.6 6 1977-07 23.2 7 1977-08 26.8 8 1977-09 48.4 9

Dear R experts, For quite some time I have been trying to solve a mistery of reading a seemingly trouble-free text file. The data is temperature reconstruction arranged as a huge grid, preceded by seven "header lines" (which you see better if file is opened in Firefox or Chrome). This is the data (gridded temperature reconstruction)

Folks, This question is somewhat related to a previous posting of mine. I just can't seem to create a generic solution. Here is a function that I found searching around the internet: splitIt <- function(x, n) {split(x, sort(rank(x) %% n))} I use it like so: > splitIt(1:12, 2) $`0` [1] 1 2 3 4 5 6 $`1` [1] 7 8 9 10 11 12 Or > splitIt(1:12, 4) $`0` [1] 1 2 3 $`1` [1] 4 5 6

Hi Chaps, A couple of Sun Netra t105 have been donated to the CentOS Project. The machines are located in London and I was wondering if anyone in the area might be able to host these machines for us ? They come with 19" rack rails. We would need access to some - but not a whole lot of - bandwidth. We plan on using these machines in developer roles, for code testing and sandbox builds.

dovecot-2.0-0.10.beta6.20100630.el6.x86_64 on CentOS 6. Virtual machine with 1 GB of RAM on VMWare. The configuration is more or less stock. Postfix receives then delivers to Dovecot. IMAP with mbox. Only one user account, but shared by several people via webmail (Roundcube webmail in Apache on the same machine). No other MUAs. 100k new messages per month, inbox is rotated monthly into a

Morning chaps, From my understanding the puppet master must have a hostname of "puppet". Is this correct? I''d like to be able to call this box whatever I like. I think that I can do that within /etc/puppet/puppet.conf. -- John Maclean MSc (DIC) Enterprise Linux Systems Engineer -- You received this message because you are subscribed to the Google Groups "Puppet

So, in a thread on HA a user asked if some logo was the official one for Vorbis. It turned out not to be, but everyone agreed the official logo was ugly and a bad idea to add on any portable player compilant with Vorbis (or other Ogg media for that matter). The chaps, me included, started a discussion of a redesign, but truth be told, if Xiph isn't interested in a redesign, there's no

Chaps, Perhaps this question is a little basic for this list but I''m not really sure of the simplest method or best tool for the job. I''ve created some images with `dd=/dev/zero ....` and I''m using them for the domUs now. Some of them have been running for a few months with no probs. Trouble is that I''d like to create a separate partition within the domU.

Hi Chaps, Is there a way to detect/highlight poor quality voice calls going through an asterisk server? Was thinking of picking up a cdr record or some other variable showing poor quality on calls when the internet is having issues. Is there any qos or poor audio quality variables available?

Hi chaps, So my general problems with disks disappeared once I understood it was an SELinux problem. However I''m still finding in the DomU when I run through my kickstart that I''m getting an error which says: "Error processing drive: xen-vbd-51712 ........ this drive may need to be reinitialized" See: http://d.pr/i/YrH8 If I go ahead and reinitialize it, the
