Full_Name: Yongchao Ge Version: 1.8 OS: Windows XP profesional Submission from: (NULL) (146.203.2.152) The R installation is fine on Windows XP, but when I started to open the R program, then it pops out this message: "R for Windows GUI front-end has encountered a problem and needs to close. We are sorry for the inconvenience....." The error signature is: AppName: rgui.exe AppVer:

In trying to execute this line in R (Version 1.7.1 (2003-06-16), under windows XP pro), with the randomForest library (about two weeks old) loaded, the program crashed: bost4rf <- rfImpute(TargetDensity~.,data=bost4rf0) Specifically, an XP dialog box popped up, saying ?R for windows GUI front-end has encountered a problem and needs to close.? That was the dialog saying asking whether I

hi all, It's not clear to me how (or if) I can pass multiple values for lty to a key in xyplot? I've tried: lines=list(lty=1:3), to no avail. Do I need to use something other than auto.key? (Deepayan, if you're out there, I have your book and must admit the answer isn't jumping out at me.) thanks in advance! Michael Folkes example code: #____________________________

Hello all, I've been using binconf (package Hmisc) at a range of alpha values and noticed that using the 'Wilson' method when alpha is larger (i.e. narrow CI), results in the upper value being smaller than the lower value. The 'exact' and 'asymptotic' methods give results in the realm I'd expect. But the help file suggests: "Following Agresti and Coull, the

Perhaps somebody could clarify for me if the following is a floating point matter or otherwise, and how am I to correct for it? > floor(100*.1) [1] 10 > 100*(1.0-.9) [1] 10 > floor(100*(1-0.9)) [1] 9 Thanks!

Dear R-users, I haven't found a way in the searchable archive to overplot a contour (lines) over a surface. I have a (n,m) matrix that represents sea surface temperature that I have plotted using image.plot(), filled.contour() or image(). I would like to overplot this image with some contour lines of mixed layer depth values(same size matrix). How can I do this? Any help is appreciated,

I'm looking for an optimal approach to access Oracle databases via RWeb applications. I'm new to R but familiar with programming functions and web pages for the S+ Statserver. I'm now going through the motions of migrating S+/Statserver applications to R/RWeb as a feasability exercise. I can access databases using ODBC directly in R or S, and using Statserver, but I have not succeeded

I'm using RODBC to read an excel file (not mine!). But I'm struggling to find a way to preserve the column names that have a numeric value. sqlFetch() drops the value and calls them f1, f2, f3,... (ie field number). this is a different approach from read.csv, which will append "V" prior to the numeric column name. sqlFetch isn't so helpful. Is there a way to get the

Hi everyone, I have two questions: I would like to get confidence intervals on the coefficients derived from the optim() function. I apply optim() to a given function f > res <- optim(c(0.08,0.04,1.),f,NULL,method="L-BFGS-B",lower=c(0.,0.,0.)) And I would like to get the p-value and confidence intervals associated with > res$par My second question deals with error message. I

Hello all, I'm hoping to convert a decimal value for week of the year back to a date object. Eg: strptime(paste(2010,1:52,sep=" "),format="%Y %W") I expected (hoped?) this would give me the date for Monday of each week. Instead, it's giving me 52 values of today's date. Where am I erring? Thanks Michael _______________________________________________________

Hello r-help, I am trying to collapse or aggregate 'some' of a data frame. A very simplified version of my data frame looks like: > tester trip set num sex lfs1 lfs2 1 313 15 5 M 2 3 2 313 15 3 F 1 2 3 313 17 1 M 0 1 4 313 17 2 F 1 1 5 313 17 1 U 1 0 And I want to omit sex from the picture and just get an addition of num,

Hello all, After beating my head against the wall for a few hours, I give up. I have two problems. 1. If I use seq() to generate a POSIXct series that crosses a daylight savings to stardard time change I get two values for the first day of change. The time change is Nov 6,2011. The value for Nov 7 turns into 23:00 on Nov 6, thus two values for Nov 6. (see below) So I put a time value (noon)

Hi, Can we attach a more descriptive "label" (I may use the wrong terminology, which would explain why I found nothing on the FAQ) to variable names, and later have an easy way to switch to these labels in plots? I fear this is not possible and one must enter this by hand as ylab and xlab when making plots. Thanks in advance, Denis Chabot

Help I can produce the hexidecimal equivalent of a decimal number but I am having a hard time reversing the operation. I'm good for hex representations to 159 and am close to extending to 2559. The archives are not clear on the existence of a function for this task. Is there one? Here is what I have got so far: #Good for hex values to "9F" as.decmode<-function(as.character(x)){

I read answers to questions including the words "tapply" and "weighted.mean", but I didn't understand either the problem (data) or the solution provided. Here is my question ... > dat[1:10,] GROUP VALUE FREQUENCY 1 2 2 78 2 2 3 40 3 2 4 16 4 2 5 3 5 2 6 1 6 2 8 1 7

Thank you for the information that you have passed on to me. My own research has found that ftruncate is quite happy to set a file to the same size that it is already, so something else must be causing the problem. The comment before the ftruncate in set_share_mode says the file is being truncated just for safety, so normally it is probably not necessary to truncate the file. Regards, Tim >

Hi all, I've got R for windows 2.3.1 I'm trying to modify my lattice histograms. The following does reset the y-label to blue, but I cannot turn off the label (alpha=0), nor shift label position (I'm assuming that is what lineheight is for). Is 'lineheight' the equivalent of 'line' in mtext? Am I erring somehow? Thanks!

Hello I am trying to add a ternary plot as a corner inset graph to a larger main ternary plot. I have successfully used add.scatter in the past for different kinds of plots but It doesn't seem to work for this particular function. It overlays the old plot rather than plotting as an inset. Here is a simple version of what I'm trying. Note that if I change the inset plot to be an ordinary

Hi, I am having problems using .First() with the Mac OS X gui version of R 2.7.2 (under OS X 10.5.5); .First is ignored on startup. .First() does work in the command-line version of R under Mac OS X but my specific task requires the gui version. I can find no reference to this issue in the Mac OS X FAQ or in other manuals, does anyone have a solution for this? Thanks, Ian -- Ian Jonsen
