I've just encountered a segfault when using DierckxSpline::percur function. Below is the minimal example which triggers the error: --- library(DierckxSpline) x <- 1:10 y <- rep(0, 10) pspline <- percur(x, y) --- *** caught segfault *** address (nil), cause 'memory not mapped' Traceback: 1: .Fortran("percur", iopt = as.integer(iopt), m = as.integer(m), x =

Reshape version 0.5 =================== Reshape is an R package for flexibly restructuring and aggregating data. It's very much pivot table inspired, and it (hopefully) makes it very easy to view your data the way you want. You can find out more at http://had.co.nz/reshape The big news in this version of reshape is that I've renamed all the functions so they no longer conflict with any

Note that package.descripton() is deprecated in R-1.9.0. You have to use packageDescription() instead. Jim James W.

When I saw the subject of the original message on R-help, I was 95% confident that I knew the answer (before I had seen the question). This made me think that perhaps for some functions there should be a 'Troubleshooting' section in the help file. The current help file for 'integrate' does say, as Sundar points out, what the requirements are. However, I think more people would

Any way of mixing bold and plain fonts in text() (or mtext(), etc.)? I'm looking for a solution that doesn't require manually spacing two calls of text(). For example: text(x=0,y=0,labels="bold(Figure 1.) plain(This is a picture.)") where "Figure 1." is bold-faced and "This is a picture." is plain-faced. I've tried to trick plotmath into doing this but

I'm new to lattice and can't figure out what the problem is with the following example: ######################### > library(lattice) Loading required package: grid Attaching package `lattice': The following object(s) are masked _by_ .GlobalEnv : xyplot The following object(s) are masked from package:base : levels > test.data <- data.frame(x=rnorm(100), +

Hi All: This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess. See if it got corrected now (I do not have

An example from the sos package: Its DESCRIPTION file says Author: Spencer Graves, Sundar Dorai-Raj, and Romain Francois. However, the package includes a findFn function, whose help file includes an Author(s) section, which reads, "Spencer Graves, Sundar Dorai-Raj, Romain Francois. Duncan Murdoch suggested the "???" alias for "findFn" and contributed the code for

Full_Name: Sundar Dorai-Raj Version: 2.8.0 OS: Windows Submission from: (NULL) (76.220.41.126) The following code crashes R: library(tcltk) tt <- tktoplevel() tc <- tkcanvas(tt, yscrollcommand = function(...) tkset(ts, ...)) > sessionInfo() R version 2.8.0 (2008-10-20) i386-pc-mingw32 locale: LC_COLLATE=English_United States.1252;LC_CTYPE=English_United

First of all, I do not understand why conversion to characters are not allowed. That's what Sundar's solution is doing implicitly (but more elegantly). Here's a test of all three. See the function definitions below. > f1 <- factor(sample(letters[1:3], 1e4, replace=TRUE)) > f2 <- factor(sample(letters[3:5], 1e4, replace=TRUE)) > f3 <- factor(sample(letters[5:7],

Another question about lattice: Is there a way to use plotmath in the labels and strips? E.g. xyplot(y~x|group,data=test.df, panel=function(x,y,subscripts,df) { llines(x,y,col="black",lwd=2) llines(x,df[subscripts,"lowerCI"],lty=2,col="#aaaaaa") llines(x,df[subscripts,"upperCI"],lty=2,col="#aaaaaa") },

Hi All, This question was brought up some time ago but I never saw a reply so I'd like to bring it up again. When using ROracle package (version 0.5-5), I am unable to run any queries that are greater than 4000 characters in length. If I do, I get the following message: Error in oraPrepareStatement(con, statement, bind=NULL) : RS-DBI driver: (too long a statement -- it must has less than

Any ideas on adding text to persp plots? The perspp function from S-plus is not implemented. I'm using R1.3.0 on Win2000.

Full_Name: Sundar Dorai-Raj Version: 1.8.1 OS: Windows 2000 Professional Submission from: (NULL) (12.64.199.173) I discovered this problem when trying to use princomp in package:mva when a column in my matrix was all zeros and I set cor = TRUE (thus division by 0). Doing so hangs R, never to return. I have to shut down Rterm in the Task Manager and lose all work from the current image. I tracked

I am grateful to Andy Liaw, Douglas Grove, Brian Ripley, Tony Plate, Dirk Eddelbuettel and Sundar Dorai-Raj all of whom got together and drilled sense into my skull. I would like to take some effort into explaining what the question was, that I was grappling with, and the (nice) R way of solving the question. My apologies: I am still a victim of too many years of writing C, so I'm a bit dense
