I recently installed R version 2.01 for OS X (version 10.3.6). I now get the following error message when I try to use the postscript function: Error in get(name.opt, envir = envir) : Object ".PSenv" not found This did not happen in previous versions of R (i.e. 1.9). I do not get this error message when using the pdf graphics device driver. Thanks, Jeff Freedman

Hi - I'd like to have the area between 2 lines on a x-y plot be filled with grey, but I haven't had any luck using polygon or rect. (In reality, I'd like to do this for twice - once for a low group and once for a high group - and then I'd like to plot a set of data points for a 'normal' group together with these 2 grey areas.) Here's a simple example of the 2 lines:

Since installing R 2.14.0 on my Mac (a Mac Pro running 10.6.8) an issue has arisen when using the vi editor in conjunction with the edit() command. More specifically, commented lines disappear from edited functions when using [functionname.R] <- edit(). That is, if you have created a function called “test.func” as such: function () { # This is a test ex _ 4 duh <- seq(1, 10) fuh

Greetings, I'm having a problem with something that I think is very simple - I'd like to be able to use the 'sapply' and 'by' functions in 1 function to be able (for example) to get regression coefficients from multiple models by a grouping variable. I think that I'm missing something that is probably obvious to experienced users. Here's a simple (trivial)

Hi - I apologize for the 2nd post, but I think my question from a few weeks ago may have been overlooked on a Friday afternoon. I might be missing something very obvious, but is it widely known that the aggregate function handles missing values differently depending if a data frame or a formula is the first argument ? For example, (d<- data.frame(sex=rep(0:1,each=3),

I've got a list of 5 matrices that are each 5 x 6. I'd like to end up with a 5 x 6 matrix that contains the mean value of the 5 original matrices. I can do this by brute force, but there must be a better way than making each matrix into a vector and then remaking a matrix thanks very much for any help david freedman ll=list(structure(c(9.7, 17.6, 20.8, 24.1, 33.8, 14.5, 25.7, 29.8,

Hi - I'd like to construct and plot the percents by year in a small data set (d) that has values between 1988 and 2007. I'd like to have a breakpoint (buy no discontinuity) at 1996. Is there a better way to do this than in the code below? > d year percent se 1 1988 30.6 0.32 2 1989 31.5 0.31 3 1990 30.9 0.30 4 1991 30.6 0.28 5 1992 29.3 0.25 6 1994 30.3

Dear R, I've got a data frame with children examined multiple times and at various ages. I'm trying to find the first age at which another variable (LDL-Cholesterol) is >= 130 mg/dL; for some children, this may never happen. I can do this with transformBy and ddply, but with 10,000 different children, these functions take some time on my PCs - is there a faster way to do this in R?

Dear R-help list, I've got a data set in long format - each subject can have several (varying in number) measurements, with each record representing one measurement. I want to assign a sequence number to each measurement, starting at 1 for a person's first measurement. I can do this with the by function, but there must be an easier way. Here's my code - id is id number, age is

Dear R users, I am not asking questions specifically on R, but I know there are many statistical experts here in the R community, so here it goes my questions: Freedman (1982) propose an approximation of sample size/power calculation based on log-rank test using the formula below (This is what nQuery does): (Z(1-?/side)+Z(power))^2*(hazard.ratio+1)^2 N =

Dear helpers. I often need to make dichotomous variables out of continuous ones (yes, I realize the problems with throwing away much of the information), but I then like to check the min and max of each category. I have the following simple code to do this that cuts each variable (x1,x2,x3) at the 90th percentile, and then prints the min and max of each category:

Hi Charles and Jonathan, I am going through my over 300 unread NUT messages, and I just discovered this one from mid-December. At the time, I was trying to clean up the tripplite subdriver of newhidups, but never got the information I needed. I have enabled this driver now, but it is marked "experimental". The driver is still incomplete, in the sense that there are many unmapped device

Hey I recently picked up a couple SMART1000LCD TrippLite UPS's. These are similar to other usb ups's that have been mentioned on the list in the past few months. I tried a few patches posted last month and got some amount of success. That being said, I am thus far unable to get much love from the actual upsd itself. Any pointers in terms of what I may need to change or what help I can

Faraway's book titled "Practical Regression and Anova using R", with full text available online at: http://cran.r-project.org/doc/contrib/Faraway-PRA.pdf refers to a data set, stat500, which compares midterm and final grades. It can be used to illustrate similar concepts. A google search for faraway.zip will locate the actual data. --- Date: Sun, 15 Feb 2004 10:37:08 -0800

Dear Members, Even though Gluster team is growing at a steady phase, our aggressive development schedule out phases our resources. We need to expand and also maintain a 1:1 developer / QA engineer ratio. Our major development focus in the next 8 months will be towards: * Large scale regression tests (24/7/365) * Web based monitoring and management * Hot upgrade/add/remove of storage nodes

Hi all! I am trying to develop a plot a figure in which I would like to show the odds ratios obtained from a logistic model. I have tried with the dotplot option but no success. Could you help me? Is there any option when modelling the logistic model in R? Thank you in advance
