I've got a data frame that looks like this: subject foo bar 2 1.7 3.2 2 2.3 4.1 3 7.6 2.3 3 7.1 3.3 3 7.3 2.3 3 7.4 1.3 5 6.2 6.1 5 3.4 6.9 ... That is, I've got multiple rows per subject. I need to compute summaries within categories where the subject has the same number

I am generating some graphs (on GNU/Linux using R 1.5.x) for a PowerPoint presentation my boss is giving next week. He just tried cut/pasted a plot off of a PDF file I had created, but he complained that the fonts were too small and fuzzy, and that he couldn't change the background. I have been playing with png(bg=transparent), but I am not sure what appropriate height,width parameters and

I am getting ready to load a bunch of data into R. The data is all numeric, but some of the numbers are integer codes representing non-numeric semantics. What is the best way to "fix" the data frames so that these compenents are recognized as "factors" or "ordered", as appropriate? Can I "assign" to some attribute of the data frame component, like the

Here is the summary on predict when using an arima0 object: The arima0 object must be based on a time series vector. That is; x <- ts(xm1, frequency=12, start=c(1975,1)) x.ar <- arima0(x,order=c(1,1,1)) predict(x.ar,n.ahead=3) Thanks so much to Prof. Brian Ripley and David Brahm and other! Sincerely, Erin Hodgess

I'd like to generate some plots like you'd see on the old "normal probability graph paper", like the first plot in: <http://www.itl.nist.gov/div898/handbook/eda/section3/normprpl.htm> except the horizontal scale would have 1%, 5%, 25%, 50%, 75%, 95%, 99%, or similar quantiles, with associated tick/grid lines. [still hunting around for a good example...] something like

I"ve got a data frame with a selection of columns I want to compute a rank-order correlation matrix from without disturbing the original data frame. foo[,c("a","b","d","f","g")] What I wanted to do, intuitively, was: > cor(rank(foo[,c("a","b","d","f","g")])) but rank in that context

I've got a set of data that are weighted by a largish integer (ranging from about 50K to 1.5 million). I'd like to plot CDF's for this data taking into account the weighting. What do you recommend?

I want to write a function to take an argument as the response variable of a linear model, e.g. to do anova's across a list of variables, something like the following (except, of course, this doesn't work): function(x) { anova(lm(x ~ my.factor,data=my.data)) } The x in lm() above is getting evaluated at the wrong level. How can I make this work? -- Russell Senior ``The two

Hello. I have been browsing the R- manual and not seen any direct implementation of Factor analysis. Is there anyone out there who has run Factor Analysis with R?

hi, all. I use R on a unix (linux) box and am quite happy with it. However, sometimes I need to create a graph that needs to be used with Microsoft Word or Powerpoint (ug). I can create a png or jpeg format picture, but the text look pretty crummy because jpeg is bitmapped. I can also create a PS/EPS version (my preference), but then it doesn't display properly in word or powerpoint (but it

I am writing a little abstraction for a series of tests. For example, I am running an anova and kruskal.test on a one-factor model. That isn't a particular problem, I have an interface like: my.function <- function(model,data) { print(deparse(substitute(data))) a <- anova(lm(formula,data)) print(a) if(a$"Pr(>F)"[1] < 0.05) { pairwise.t.test(???) }

Dear all, I have a lot plot graphs and i would like to save them. One solution is to use the grab function with xv. But it is tedious.... So is there a R function that can save automatically the result of a plot in a gif or ps or bmp file Thanks Olivier -- -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- Olivier MARTIN phone: (33) 04 76 61 53 55 Projet IS2

Dear R-helpers, I recently upgraded to R 1.9.0 in my computer at work and at home: 1.-The computer at home has Windows XP and Office XP and it seems to work perfectly and I copy-paste graphics perfectly. 2.-The computer at work has Microsoft Windows 2000 (5.00.2195 Service Pack 2) and Word 2000 (9.0.4402 SR-1) I cannot copy-paste windows metafiles into Office applications in my computer at

Greetings List, I am conducting some large simulations using R. As a result, I get many plots but I'm having some trouble with including some of them in a Microsoft Word document. Can any one tell me the easiest method of having copies of the R-graphs in the Word documents? Best regards Mahmoud [[alternative HTML version deleted]]

Dear R-listers, I got an error when I try to plot two grouped data into a single win.metafile device: library(lattice) trellis.device(device="win.metafile",color=F,filename="Profiles-Var1.wmf") par(mfrow=c(1,2)) # First plot xyplot(log(v)~t|id,data=Con.20, main="Group A: Control, Var-1", xlab="ocasion",ylab="var1", panel=function(x,y) {

Hi, how can I save an image as a metafile? I know within windows you can do a right click and then 'save image as metafile' but I use Mac OS X...I know as well that mac users have a right click as well, but it does not work. Is there a command in R for saving images as metafiles? Regards, mentor -- View this message in context:

Hi all I am doing some stats work for a group of biologists who require windows metafiles (*.wmf) for their publications. To create these, I appear to have two choices: 1. Restart my machine in Windows and use savePlot 2. Keep my machine in linux, save as another format, then convert. I'd rather stay in linux; but how do I get wmf files? I looked at using ImageMagick's convert,

Hi Folks, I see that people have been discussing the win.metafile device on the list since before 2000. Yet I have never seen this on a Linux distribution of R. Is this because the device works by making calls (GPL calls of course!) to a proprietary Windows library? In that case I can understand that it would be far from kosher to implement it on Linux. But I'd like confirmation. I must

Hi All, I need a file which I can import to MS Word, I'm trying win.metafile(), but it does not seem to support multiple print commands at once (please see below).
