I would like to have a function that inputs a file name, then reads that data file and does various stuff to it. Something like: doit<-function(filename) { x<-scan("~/rstuff/data/"filename) #for example, if filename is a0.dat, it will scan("~/rstuff/data/a0.dat") ... } Can someone please tell me how to do this? Thanks for any help! Bill Simpson

Continuing to try to customize my environment for using R under Windoze, I experimented with installing a package from CRAN in a local library ``Lib''. I created the directory ``Lib'' in the folder in which R starts, and then executed > install.packages("abind",lib="Lib") Everything went according to form (I got prompted to choose a mirror, etc.) until

Hi R users, I'd be interested in what R users think about social networking around all things R. For this, I've set up a social network @ www.rstuff.socialgo.comand it would be great if you could post your comments on the forum created for this discussion. The News section has feeds from some of the R related blogs I've been following. I'm hoping for a central resource that keeps

I've been having some strange problems with R CMD check in the last couple of days, but now believe I have localized the issue. I had been running Ubuntu Hardy on one drive and then upgraded to Jaunty, but put Jaunty on a different drive. I continue to be able to boot Hardy when I wish. I soft-linked my R working area i.e., /home/john/Rstuff ----> /media/lnx804/home/john/Rstuff

Dear R Users, I am a beginner in R programming and need some help with a simple plotting problem that i am having. My dataset consist of three columns: first one has data_id, second is the date and third is the actual data itself corresponding to each date. The date ranges from 1/1/2000-12/31/2009. I am trying to plot my data versus the dates as a long term time series but

Using R-2.8.0 and R-2.8.1, I get behaviour like this: R version 2.8.0 (2008-10-20) Copyright (C) 2008 The R Foundation for Statistical Computing ISBN 3-900051-07-0 [....] > Sys.getenv("LD_LIBRARY_PATH") LD_LIBRARY_PATH

I include the argument pty="s" to image, but still when I make an image by the method > postscript("rstuff/test.ps") > tauseq<-seq(0,1,.5) > cif2d.image(x,,y,tauseq) > dev.off() the image plot created is NOT square. I thought pty="s" would make it square. Generally it would be nice if the image saved to disk were like the one we see while in R

I read through the "Writing R Extensions" and the "Debugging in R" website (http://www.stats.uwo.ca/faculty/murdoch/software/debuggingR/), looking for some hints about how to solve the issue of debugging problems encountered during the "R CMD check" process, but nothing seems to be mentioned about addressing issues encountered. Specifically, I am working with the R

Hi, I have been trying to figure out how to use the nonlinear regression to fit the cumulative lognormal distribution to a number of data points I have but I am a new R user and I cant quite decipher the notes on nonlinear regression. Any help in this regard will be greatly appreciated, my email address is mmiller at nassp.uct.ac.za

I have been trying to use lavaan (version 0.4-7) for a simple path model, but the program seems to be computing far less degrees of freedom for my model then it should have. I have 7 variables, which should give (7)(8)/2 = 28 covariances, and hence 28 DF. The model seems to only think I have 13 DF. The code to reproduce the problem is below. Have I done something wrong, or is this something I

I recently became aware of the article by Ai and Norton (2003) about how interaction terms are problematic in nonlinear regression (such as logistic regression). They offer a correct way of estimating interaction effects and their standard errors. My question is: Does the glm() function take these corrections into account when estimating interaction terms for a logistic regression

Dear list, I came across a behavior that IMHO is somewhat undesired when calling '$field()': If the field name whose value you're trying to get is *not* a valid field of the Reference Class, then R doesn't stop there with an error, but scans through all enclosing environments/frames. The result is something similar to calling '|get(<objname>, inherits=TRUE)|'
