In R, what is the best way to convert z-scores (Normal distribution) to a percentiles, and vice-versa. (I'll be looking to do the same with other distributions eventually.) === Peter Petto <ppetto at ppetto.com> Bay Village, OH 440.249.4289

I need to use an existing windows 7 installation in a virtual machine form a libvirt host running Ubuntu 12.10. Windows 7 installs on two partitions. There a 100MB boot partitiona and then the main partition for the installation. If I boot the laptop (which dual boots), I can select Windows 7 and boot it just fine, or alternative Ubuntu. If I select /dev/sda1 in the virtmanager as the source

In order to ease my students into the R environment I am developing a package which installs a variety of utility functions as well as slightly modified versions of some standard R functions -- e.g. mean, hist, barplot, .... In my versions of these standard R functions I either add options or alter some defaults that seem to create difficulties for most of my students -- for example, when they do

Hi- I have about 20 groups for which I know the mean, variance, and number of points per group.

Hello all Sorry for the repost, but I believe this is essential for Aastra phones to use directed pickup with BLF in 1.2 (and it's still experimental in 1.4 I think). pickup-mgernoth-2006-07-28.patch.txt If anyone knows otherwise than that this is still required in latest 1.2 or 1.4 please reply with success/failure stories. Any info would be appreciated. We can get directed BLF pickup

Orca is a daemon written in Python and C which presents the contents of a Gnome screen to a blind person in speech or braille. It is on the CentOS 5.6 disks. Has anyone on this list used it? If so, what was your experience? I am developing the BrailleBlaster tactile literacy application. Since I am both blind and deaf, I will be using a braille display. I also need to make sure that the

hi- in r 1.1 on windows 2000 with length(AU) of 35833 AUcap30<-0 for(i in 1:length(AU))AUcap30[i]<-min(30,AU[i]) took over an hour on pentium II 300 mhertz (I esc'ed before it finished) but AUcap30<-AU for(i in 1:length(AU))AUcap30[i]<-min(30,AU[i]) is very quick (a few seconds) Is this performance difference common in r (ie is linux the same way)? Are there other tricks

Hi again, this is a follow-up of my previous post : I've noticed that > attr(first.list[[1]]$size.ecdf,"call") gives ecdf(test.moms[, "m.pxs"]) and that there is no "test.moms" field in my records (a local variable named test.moms was used inside a function, but it was stored under another name in the list, outside the function) May this be the answer (and

Hi- I wanted percentage labels on a qqnorm x axis. I used the following: #make up some data jt<-rnorm(100) #qqnorm with percentile x labels qqnorm(jt,axes=F,xlab="Percentiles") box() l<-c(1,5,10,30,50,70,90,95,99) axis(1,at=qnorm(l/100),label=l) which was ok for this data set. Does anyone have a more general solution which would allow one to specify the number of x labels
