Dear all, Maybe this has something to do with R crashing? When my R version crashes, there is Rgui.exe still running in the background (i.e. W2K's task manager recognises it only as a process, which apparently is using almost 100% of the CPU). I can reproduce that by "using" the SJava package (from Brian Ripley's homepage, as suggested on http://www.omegahat.org/RSJava/).

Hi R lovers 2 questions: 1) I'd like to know how to clean the title, the sub title or the labels of a graph. I know how to redefine it with the function title() but it overwrites the previous title and do not replace it 2) How could I clear a whole plot (for example in a multiple figure environment) thanks for your help vincent

Hi, I was trying to draw an empirical distribution function with uniform confidence bands. So I tried to find a way to calculate values of the Kolmogorov-Smirnov Distribution but failed. I guess it must be hidden somewhere (since the ks-test is implemented), but I was unable to find it. Is there any way to do this? Thanks Leif Boysen

Hi I have two lots of numbers which I would like to histogram using the hist() function. For comparative reasons, I want them to be on the same scale, which I can use the xlim and ylim options to achieve. However, having them on the same scale is meaningless unless they have the same "breaks". Consulting the documentation, there are 4 ways of defining the number of breaks, only one

Dear list, I would like to study the dynamics of functions using R (instead of mathematica e.g.), i.e. the behavior of points under iteration of a function. So I tried (in vain) writing a function myfunction <- function(f,n,x){...} in order to compute f^{n}(x), f^{n}(x) being the function f composed with itself n-1 times. n is a natural number, and the argument x is the abscissa of the point I

Hello, I have a question about using the layout command within a function. I've written function that uses layout to create a figure from 2 plots. This works fine to create a figure. When I use par(mfrow = c(2,2)) to create multiple plots, it seems that the layout command resets the mfrow parmeter. Is there a way for me to avoid this problem? For example practice<- function() {

Hello all, I'm a new member in this list and, also, a new R user and need some information about Resistant Smooth (using medians). The method I need of Resistant Smooth is the 4253H one and I didn't found how to perform that in R. Does anybody have an idea? Thanks, Henrique.

Dear R help, I'm pretty new to R and would be grateful for help. I have 11 data.frames, each with 3 columns of data. Each has the same row.names, however these are not sorted. Please tell me the best way to sort these (by row.names) and secondly the best way to extract data columns from these to form a merged table. Thanks a million Aedin

Dear All, I've been trying to format a plot output using par() with mfrow, fin, mai, etc and basically it's proving to be a pain. I searched on google and found that Paul Murrell had written a grid Graphics program which seems perfect. However, when I try and use say viewport() I just get a function not found error. Can someone tell me what I'm doing wrong please? Thank-you

Dear R Users, I suppose this is a school boy question, but here it is anyway. I'm trying to re-create the residuals for a poisson GLM with simulated data; x<-rpois(1000,5) model<-glm(x~1,poisson) my.resids<-(log(x)- summary(model)$coefficients[1]) plot(my.resids,residuals(model)) This shows that my calculated residuals (my.resids) are not the same as residuals(model). p 65 of

Hi R lovers! I have discovered recently that graph can be exported from R in a Latex compatible file thanks to the pictex command I would like to know if there is the equivalent while exporting datas. Let's say I have a matrix, a data.frame or a list that I would like to export as a flat text file that is immediatly transcripted into a table into latex Is there a macro or package that could

Undoubtedly a simple question: I've looked at order() and sort() in the help pages for R1.7.1. It doesn't appear that these functions are immediately suited to doing the same thing as PROC SORT DATA = BLAH; BY X Y Z; RUN; in SAS. I have also checked Frank Harrell's Hmisc library. Could someone point me in the right direction so I can sort by the levels of Z within the levels of

Hi, is there a way to plot distribution curves (say normal or chi sq etc) from within R? For example I looked up the *chisq family of functions but I'm not sure as to how I would use them to generate a plot of the chi sq distribution (for arbitrary d.o.f).

Hi, I'm a recent R convert so I haven't quite figured out the details yet... How do I select one variable by another one? Ie if I want to draw the histogram of variable X only for those individuals that also have a value Y in a certain range? In STATA I would give something like: histogram X if ((Y>=A & Y<=B)) (The data is for individuals and each individual has a number of

Dear R-"helpers"! May I kindly ask the pure statistics-experts to help me for a purpose which first part is not directly concerned with R. Consider two distribution functions, say f and g. For both, the median is smaller than a half. Now, the multiplicative or additive linkage of both distribution leads to a new distribution function, say h, whereas the median of h is greater than a

I have a data file read into a data frame. For example, V1 V2 V3 V4 1 1 1 3 4 2 2 3 5 10 . . . . . . . . . . n V1[n] V2[n] V3[n] V4[n] to n=many thousand I want to plot a graph with many line segments, where v1[i]=x1, v2[i]=y1, v3[i]=x2, v4[i]=y2 for i=1,n. This seems relatively simple in theory but I've spent quite a bit of time trying to make it happen with

Hello R lovers I have written a little cute function to count the number of missing value per row in a matrix and return the percentage of missing value it takes a lot of time to run with a 1000 rows matrix I'd like to know if there is a function already implemented to count the number of occurence of a given values in a vector For information, here is the function count<-0 for (i in

Dear R-Users, I want to ask a question for a colleague of mine. He wants to put a character vector and a numeric vector into one matrix and still have the old character and numeric type for the respective columns. Unfortunately, I am just starting using R and I could not help him. Is there an easy and straightforward way to do this in R? Maybe a little example facilitates understanding our

Hi I can't get R to connect to the internet. I am running R 1.7.1 on Windows XP and whenever I try to download packages etc from within R using the internet, it fails. OK so I am behind a firewall and use a proxy server.... SO, if I go to my MS-DOS prompt and type: RGui.exe --internet2 everything works.... BUT i can't set up a shortcut for this as Windows (I hate Windows) complains

Dear all, is there any function to calculate the center of a polygon mass in R? Actually I need to find the best location within polygons to place labels. Thanks for any hint Jens Oehlschl?gel -- COMPUTERBILD 15/03: Premium-e-mail-Dienste im Test\ --------...{{dropped}}
