Full_Name: Mark Bravington Version: 2.0.1 OS: Windows XP Submission from: (NULL) (140.79.22.104) 'sys.on.exit()' doesn't seem to be working, since R1.7.1 at least: soe.test <- function() { on.exit( cat( 'In exit code\n')) str( sys.on.exit()) # should display "language..." I think 12 } (A similar bug was apparently fixed for version 0.65!)

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

R1.7.1/Win2k: Apologies if this posts twice - the first message was not in plain text. I have looked in help.start() and tried typing "crossprod" and "%*%" into the RGui to get an idea for what R is using as internal algorithms for its matrix computations/manipulations... to no avail. Could someone point me in the direction of some documentation? All I get for

Anybody out there successfully using the Salford Fortran compilers with R? I have created a DLL using the Salford FTN95 compiler and it works in as far I can dyn.load it, run the routines and get the right answers back. Unfortunately subsequently, sometime later, the Rgui crashes (access violation I think from the DrWatson log). The crashes depend on whether or not I paste the code as one

Dear R-users I have a probelm running stepAIC in R1.7.1 I wrote a program which used stepAIC as a part of it, and it worked fine while I was using the previous version of R1.7.0. However, I found the program did not work any more. Now, R produces a message which tells "Error in as.data.frame.default(data) : can't coerce function into a data.frame" every time I run the part of

I am trying to read a matrix of 5000*2000 from a csv file of real numbers in R using the scan function. I am getting an error saying that R can not read a vector > 32KB and it can't allocate a memory of 191 MB etc. What should I do. I am using R1.7.1. Thanks ===== Thanks Fairouz Makhlouf

I am wondering why my function works fine in R1.7.1 and R1.8.1 but not in R1.9.0. I thought it's an environment related problem but I can't solve it. >data weta jd 1 1 4 2 2 13 3 2 13 4 6 4 5 1 3 6 1 7 7 2 10 8 3 10 9 1 8 10 1 8 11 3 6 12 1 9 13 1 5 14 1 1 15 3 13 16 1 2 17 2 2 18 7 11 19 1 3 20 5 4

Hi, I have a data file which contains multiple data types (char and numeric) alongside with line spaces, tabs and spaces. I hope to extract out the numeric blocks of the data, probably as matrices or dataframes where each line in the data block is a corresponding row in the dataframe/ matrix. I have tried using many R read functions but they do not seem to yield the appropriate structure that

What exactly is strange, apart from posting a question as a bug report? Please do read the R FAQ and don't misuse R-bugs to ask questions. Hint: you most likely specified a non-existent time. When did your locale switch to DST in 1993? I don't know, of course (you haven't told us your locale) but I bet it was that day. That means the time you specified does not exist if your locale

Dear List members: I'm using R1.7.1 (Windows 2000) and having difficulty with scoping. I've studied the FAQ and on-line manuals and think I have identified the source of my difficulty, but cannot work out the solution. For the purposes of illustration. I have three functions as defined below: fnA <- function(my.x) { list(first=as.character(substitute(my.x)), second=sqrt(my.x)) }

Hi all, I develop and print from both Windows and Linux, and am seeing some printing inconsistencies first described about a year and a half ago by Andy Liaw (see below). Specifically, the line widths on my windows plots are about 5 times smaller than that on Linux, and my windows printouts do not match what my screen looks like. However, if I print to a pdf file first, then I can get accurate

R1.8.0, Win2k: When I run the code lset( list( background = list(col = "white"))) xyplot ( y ~ TIME , data = foo.frame, scales = list(alternating = FALSE), ylim = c(.75,y.max), panel = function(x, y, panel.number, ... ) { panel.superpose(x = foo.frame$TIME[foo.frame$group == 1], y = foo.frame$y[foo.frame$group == 1], subscripts = TRUE, groups =

Dear R-help, Has anyone notice the problem that, on Windows (NT and XP), when printing a graph using the "File -> Print..." menu in the graphics window to print the graph, that line width seemed to be ignored in the printed output? For example, if I make a plot with plot(1:10, type="l", lwd=5), it looks right on screen, but when printed out using the menu, it looks like

Hi, I noticed the following bug while using R version 1.7.0 for Windows (and Linux): > floor(log10(1000)) [1] 2 > Here are my start-up messages: R : Copyright 2003, The R Development Core Team Version 1.7.0 (2003-04-16) R is free software and comes with ABSOLUTELY NO WARRANTY.

Win2k, R1.7.1: I am currently working with some growth curve data from a biotoxicology experiment. Each of 12 subjects had their blood drawn at 0, 2, 4, 6, 8, and 10 weeks. For the purposes of the project, it would be helpful if I were able to do the following: a. Produce 12 panels, each displaying the *same* data, with the "strip" at the top of a particular panel showing

Dear All, I am analysing some data for a colleague (not my data, gotta be published so I cannot divulge). My response variable is the number of matings observed per day for some fruitlies. My factors are: Day: the observations were taken on 9 days Regime: 3 selection regimes Line: 3 replicates per selection regime. I have 81 observations in total The lines are coded A to I, so I do not need

My question has two parts. The first is with regard to the frame or environment in which generic functions are defined in packages. It seems as though they are defined (i.e. exist as objects) in frame 1, even when defined in a package. The following is a short example: setClass("track",representation(x="numeric",y="numeric")) plotTrack <- function(x,y,...)

In checking over the solutions to some homework that I had assigned I observed the fact that in R (version 2.4.0) pnorm(-1.46) gives 0.07214504. The tables in the text book that I am using for the course give the probability as 0.0722. Fascinated, I scanned through 5 or 6 other text books (amongst the dozens of freebies from publishers that lurk on my shelf) and found that some agree with R
