Hello, are there any best practices for the length of user names? I tend to limit them to 8 characters and to follow the pattern 'first letter of the first name'+'first 7 letters of the last name' (e.g. mbaudier). But people are sometimes frustrated with having their last name truncated and I wonder if limiting the user name to 8 characters is not a kind of superstition coming

It is largely due superstition, but if you change f before calling split<-() you have split() and

I have two waves of a survey given to students at various middle schools and high schools, with student id numbers for each student. I am having difficulty reshaping the file from long to wide. My code is below: library(foreign) svy <- read.spss("studsur4.SAV") svy.wide <- reshape(svy, timevar="WAVE", idvar="id", direction="wide")

Dear All, Can R produce dot plots like the one of the following picture: http://en.wikipedia.org/wiki/Image:Dotplot_of_random_values.png ? I have tried dotchart, but no success. Thanks in advance, Paul

I have been trying to get Rgraphviz to work (I know it is from Bioconductor) unsuccessfully. Since I have no experience with Bioconductor I thought I would ask here if anyone has advice. I have installed Graphviz 2.20.3 as is recommended on the Bioconductor site but basically R cannot seem to find the needed dll files. So, even though I have added the appropriate directories to the system path R

I want to migrate my R workspace databases (e.g., .Rdata) from Windows to Linux. The R help file for "save" says that "[a]ll R platforms use the XDR representation of binary objects in binary save-d files, and these are portable across all R platforms." Is it is simple as that? Copy the Windows .Rdata file to the Linux .ext3 file system? Thanks, Derek Derek N. Eder

Howdy Folks, This release is after painstaking analysis of a memory leak that was reported by Bradley Taylor, reduced by myself, and then fixed after much work. You should all thank Bradley for finding the bizarre fix. It turns out the Ruby has a memory leak when you use pretty much any thread locking primitive other than Sync (Mutex, Monitor, etc.): http://pastie.caboo.se/10194 The fix (for

Sorry if this is too off topic, but one of the things that happens when you use a *nix box is you have opportunities to do some nifty tricks with shell scripts and whatnot to help maintain your network. Sometimes, this comes at the expense of using the tools that come with some windows software and is the result of necessity. Other times, this comes because the "nifty" tools that come

Hi, I have a class called Outlet which has_many Jacks. Apart from internal id, each jack is unique by the attribute ''color''. I''d like to iterate through each Outlet, and be able to output data for a Jack of a certain color. Say, I want to access the orange jack for the current outlet: <td><%=h outlet.jack.color[''O''].ip_address
