Re: [R] sqldf for Very Large Tab Delimited Files

Bad news! The readLines command works fine upto a certain limit. Once a few files have been written the R program crashes. I used the following code: * iFile-Test.txt con - file(iFile, r) N-125; iLoop-1 while(length(Lines - readLines(con, n = N)) 0 iLoop41) {

[R] GAM (mgcv) warning: matrix not positive definite

Dear list, I fitted the same GAM model using directly the function gam(mgcv) ... then as a parameter of another function that capture the warnings messages (see below). In the first case, there is no warning message printed, but in the last one, the function find two warning messages stating

[R] Reading table data from PDF files

All, Is anyone familiar with a way to use R to read table data from a large collection of PDF files? I'm aware there are various command lines and desktop utilities that might be able to (e.g.,) dump PDFs to text, which could then be parsed for table data. But I'm hoping there is something

You may want to look at functions like: txtProgressBar, winProgressBar (windows onnly), or tkProgressBar (tcltk package), rather than reinventing the wheel. On Fri, Feb 3, 2012 at 7:00 AM, angliski_jigit angliski_ji...@hotmail.com wrote: Hi All, I am trying to build in a progress-tracker into

Re: [R] Fiedler

Hola! This can be done with the CRAN package igraph, which contains (part of) the arpack library for computing only some eigenvalues/eigenvectors of sparse matrices. arpack gives you the option of computing a few of the smallest or a few of the largest eigenvalues/vectors. Do library(igraph)

[R] incomplete final line found on name of my sourced function file

Dear R-ers, I hope there is a really simple solution to my problem. I've written a function that I saved in an .r file. I source this file in my code. For a while it worked fine. But then when I run the line: source(F mylineplot.r) I started getting a warning: In readLines(file) : incomplete

Re: [R] incomplete final line found on name of my sourced function file

Try opening the file up in a text editor and inserting a blank line or two on the end. (There's either an EOL or EOF character missing and this trick usually works for me -- never sure why/when it happens though) Michael On Fri, Feb 3, 2012 at 4:23 PM, Dimitri Liakhovitski

Re: [R] GAM (mgcv) warning: matrix not positive definite

It is completely safe to ignore this. Here is what is going on... mgcv routine 'mroot' is calling R routine 'chol' to find the *pivoted* Choleski factor of a positive semi definite matrix. This is deliberate, and completely ok to do, but 'chol' issues a warning when a matrix is only positive

Dimitri. This has been asked a whole bunch of times on this list. Do a search on the text in the error message if you doubt me. I have this link on my toolbar: R-search:

Re: [R] Hanging -- please help decipher event report

Thanks for your reply. At line 144 I call R_CheckUserInterrupt(). I added this because otherwise, R would not respond to the user for thing like switching over to the window until the C code exited back to R. I then moved that command into a loop where it should occur quite frequently, because I

Re: [R] [fields] image.plot abends with NAs in image.plot.info

Tom, Before we go into this in detail can you double check that your second data image is OK. Just try something like image( z) where z is the matrix of values for the second image. ( the $z component of an image list) My quick guess is that the second image is all NAs due to a few

[R] ordering of factor levels in regression changes result
