I am trying to make a nice 2x1 plot and add a timestamp with comment. The pstamp function from Hmisc works nicely when mfcol=c(1,1), but when mfcol=c(2,1), the stamp winds up in the wrong place: > require('Hmisc') > opar <- par(mfcol=c(2,1)) > plot(1:10) > title(main="MAIN Title") > plot(1:20) > title(main="Another Title") > pstamp("normal

I have a data.frame which I believe is melted already and am having trouble casting it to 'wide' format. It looks something like > (x <- data.frame(ticker=c(rep("A",5),rep("B",6)), date=c(1:5, 1:6), value=c(NA,100*exp(rnorm(10,0,.1))))) > cast(x, date ~ ticker) # this does what I want with toy data But when I use my real data frame >

?unique says Value: An object of the same type of 'x'. but if an element is equal to one with a smaller index, it is removed. However, I need to keep the one with the LARGEST index.

Is there a recommended/preferred version of Linux for using with R? Is there one version of Linux that R-users prefer, and/or that works "better" with R? I am working with "large" datasets, and hope to take advantage of as much RAM as reasonable (8-32gb?).

This patch: * adds a C-based security policy translation tool to Xen (secpol_xml2bin) and removes the current Java security policy translator (Java dependencies). The C-based tool integrates into the Xen source tree build and install (using gnome libxml2 for XML parsing). See install.txt. * introduces security labels and related tools. Users can now use semantic-rich label names to put

Does anyone have experience of drupal installation under CentoOS-5.3 with MySQL database preferably accessed through phpMyAdmin. I want to install drupal more or less as an experiment, and I'm looking for a 1- or 2-page document that just lists precisely what steps to take. I've had a quick look at the official installation instructions, and I found them confusing and contradictory. --

Hi I'm trying to get Dovecot to use Drupal users password for authenticating IMAP users. But I just cant figure out how to make Dovecot understand the password hash type that Drupal 7 is using. My example user with password Teacher1 looks like this in Drupal database: $S$DZwJa.U8HXT2PvTmwCK13rGEYEvnx5DB6/hlqnfCBum4s4U7MVWU Dovecot retrieves this hash but complains that its not a recognized

Please see example code below. I have a vector ("mydata") of length 10. "mydata" can have various formats (e.g. numeric, text, POSIXct, etc) I use the matrix and data.frame functions to convert "mydata" to a dataframe ("mydf") of 2 columns and 5 rows. What is a "good" way to ensure that the format is retained when I create the

Hello all, Maybe the $subj is a little bit weird (i.e. apples vs oranges) but it is a situation i am facing at the moment: We are developing a small web site which will be mostly a CMS (more or less) and my colleagues is arguing for drupal, and i am for RoR. Maybe i can formulate the question in a different way: when to use a CMS (not necessarily drupal but e.g. Radiant CMS) and when to use Ruby

Hi folks, Last night and this morning i''ve hacked up a quick web site for coordinating our development work based on Drupal (http://drupal.org). You can find it at: http://shorewall.dyndns.org I''ve put a few ideas in there - feel free to use the comments or sign up for an account and create your own pages (particularly in the two books about development and web site work).

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am looking to set up a CentOS server for hosting a high traffic PHP site (specifically Drupal 6). I am trying to figure out what's the best way of setting up PHP. The standard mod_php seems to not be a good solution, as it requires apache to be in the prefork configuration, due to PHP not being thread safe. Something like mod_fcgi seems to be

Hello, the "man syslog.conf" explains how to filter syslog messages by facility (auth, authpriv, cron, daemon, kern, ... ) or by priority (debug, info, notice, warning, ...).

How do I retain "POSIXct" formatting when using apply, with FUN=max? #example: mydata <- rep(Sys.time(), 10) mydf <- data.frame(matrix(data=mydata, nrow=2, ncol=length(mydata) ) ) for(i in seq(mydf))class(mydf[[i]]) <- class(mydata) str(mydf) maxdates <- apply(mydf,2,max,na.rm=T) str(maxdates) #Why is the formattign now "chr", and not
