Hi, Sorry if this is an obvious one, but is there a simple way to modify the lm function to test whether a slope coefficient is significantly different from 1 instead of different from 0?

Hello, I'm using the nls function and would like to increase the number of iterations. According to the documentation as well as other postings on R-help, I've tried to do this using the "control" argument: nls(y ~ SSfpl(x, A, B, xmid, scal), data=my.data, control=nls.control(maxiter=200)) but no matter how much I increase "maxiter", I get the following error

Hello, Once again, I posted a message without a subject line. Sorry.... here is the question again. Is there a simple way to modify the circ.mean function in the CircStats package to include a vector of weights to obtain a weighted average angle? Thanks!

G'Day, I'm a little confused why the c function has the followng effect on classes - is this a feature ? My workround [ class(cc) <- c("POSIXt", "POSIXct") ] seems to do the job. Many thanks Bernie McConnell "R version 1.3.1, 2001-08-31" on NT > aa <- as.POSIXct("2001-09-23") > bb <- as.POSIXct("2001-09-24") > cc

G'Day again, I am attempting to read a large MSAccess file into R, but get memory problems. With the first 100 rows of the table ("Macca99") things, as shown below, are fine and the resulting object is 33,780 bytes. But when I read the entire table ("MaccaDiv99") which is 218,000 rows R falls over with the message: Rgui.exe - Application error The instruction at

Hi, Is there a function in R to calculate the nth root, similar to the MATLAB function NTHROOT()? Thanks, Martin Biuw [[alternative HTML version deleted]]

Dear all, I need to read in 4 sets of tab delimited data in a loop. The 4 data sets are called "simu1.dat", "simu2.dat" and so on. I know what I need on the righthand side of the read.table expression but I can't the left hand side of it to work (see the line in bold below). Can you kindly help? Many thanks. simu1 <- matrix(0,30,3) simu2 <- matrix(0,30,3) simu3

This is because, as my example showed. as a Unix use, Administrator is just a normal, unprivileged user e.g. my example Unix

Forte Agent newsreader on Wine 1.0 on Mandriva 2008.1. If I close Agent and then re-open it, its inner newsreader pane becomes dislodged as a floating section in a scrollable window. The following image (size 29k) shows what I mean. The top image is before closing and the lower image is after re-opening. http://i282.photobucket.com/albums/kk268/farry6/agent.png This happens if it's

it seems that word can not read encapsupalted postscripts generated by R I used this command postscript("output.eps",horizontal=F,onefile=TRUE) since onefile=TRUE produces an encapsualted postscript actually what I'm trying to do is to insert the postsript file into a word document since other formats like jpeg and bmp do not reproduce the same quality like postscript formats any

We've been doing our own beta testing of Dovecot 2.0-beta4 IMAP (both direct IMAP and webmail-fronted), and we've had nothing but glowing compliments from our beta users/victims. I've also been running a lone box with the latest mercurial build and that's been running just fine too. All mail data is on NFS, but I've put indexes on the local disk, which has worked just dandy so

Hi all, Forgive me if this is an obvious one.... I want to make a plot of confidence intervals from an lmList object with a collection of simple linear models (lm(y~x)) using: plot(intervals(mylmList)) and sort the plot by increasing mean values for the intercept. Is there an easy way of doing this? I've tried the "order()" and "sort.list()" functions, but I suspect

Michael, The benefits of Sphinx sound nice but one comment: The main page and the tables of contents in the other pages (at least the ones I looked at: Getting Started; Lang Ref) are so long and sparse that it is difficult to get the big picture of what is there and even to find a document unless you know what to search for. The originals were much more compact and so much better in this regard.

Hi, This may or may not be slightly off topic, but I'll stick my neck out... I want to launch an external application from R while retaining R as the active application window (with R console as the active R window). I'm using shell.exec() to sequentially open and evaluate the contents in all jpeg images in a specific folder, using the viewer specified by the file association (in my case

Johannes, You can minimize an model expression by just putting the ~ on the left and everything else on the righthand side, but I don't think that this is really what you want. In the NLS expression this would ignore the jacobian of the transformation from errors to response, and in nlrq there is the same problem, however you can adjust for the jacobian by rescaling by the geometric mean of
