Hi, I have a nicely printed table of results generated by R's > print(myresult) where myresult is a "data frame". I am trying to put this table into a powerpoint slide for presentation without re-typing and re-formating, i.e., present it as it is in the R window. This saves time when there are a lot of tables to be presented. I tried > sink("myresult.txt") >

Hi, This is more a statistics question rather than R question. But I thought people on this list may have some pointers. MY question is like the following: I would like to have a robust regression line. The data I have are mostly clustered around a small range. So the regression line tend to be influenced strongly by outlier points (with large cook's distance). From the application 's

Hi all, Although R seems to have jpeg() and png() functions that converts data into jpeg and png formated files, it doesn't have functions the other way around. Does one of R contributed packages have gif, jpeg and png image readers?

Dear R experts, Does RMySQL package handle Blob datatype in a MySQL database? Blob can represent an image, a sound or some other large and complex binary objects. In an article published by R-database special interest group, named "A common database interface (DBI)" (updated June 2003), it's mentioned in "open issues and limitations" that "We need to carefully plan

Hi, Is there a way to comment out multiple lines at once in R source code like C language's /* */ struct? This is quite useful when one is testing different sections of a source code.

Hi, To better organize a package, one sometimes wants to place some individual R files in R-ex directory (at least this is the way I understand the functionality of R-ex). But how does one organize the source R package so that R CMD INSTALL pkg will know which R files will go into the R-ex directory? In the implementation R CMD INSTALL pkg, all R files in the pkg/R directory are automatically

Hi, I think that R-tcltk doesn't have the capacity to display an image stored in memory on a tkcanvas object, am I right? I have digged around everything I can find from Peter Dalgaard and tcltk references and drew my conclusion. Can you, Peter, or some other gurus on the list, give us a pointer or two on how to proceed to solve this problem? I am afraid that it may involve writing C

Hi! I am looking for a R library by which i can load images (i found pixmap that allows it to do). But in addition i need methods to access the data, get them for example as an array or matrix to do with this data some processing. 1. Is there a method in the pixmap library to access the matrix in which the image data is stored. 2. Is there an alternative library running under MS Windows?

Hi, Thank you for the tip. I tried to re-intall R from Debian "stable", in which R's version is 1.4.0. And the installation of "mvtnorm" works. I then re-installed R yet again from Debian "unstable" (woody), in which R's version is 1.5.1. The installation of "mvtnorm" fails again with the same error message. Another package that failed with the

Hi all, Look at the following "stupid" function that is created just to show the problem: outlayer <- function(x) { inlayer <- function(z){ e1 <- parent.frame() eval(expression(y<-log(z)),e1) } inlayer(10) y } I have a compilation error when running this. My purpose is to create "y" variable equal to log(z) in the frame of "outlay". How can I

Dear R people, I have been trying to use install.package() to install packages from CRAN. The machine is a Windows 2000 with Pentium 4. The machine operates under a proxy environment. I have followed advices I found on R-help mailing list: change internet2.dll to internet.dll so that R will use the same setting as Internet Explorer uses. After I made the change, R crashes when I attempt to use

Hi all, An offline communication with B. Ripley gives the answer for whoever else may have the similar problem: Run R with a flag: Rgui --internet2 or Rterm --internet2 By the way, as Brian pointed out, this information can be found at R for Windows FAQ on cran website.

Dear R users, Is there anyone who is aware of a R or S package that has Discriminant Adaptive Nearest Neighbor (DANN) classification by Hastie and Tibshirani?

Hi, I was trying to update packages with my R 1.6 under RedHat 8.0 system. When entering this command, > update.packages() It simply says, trying URL `http://cran.r-project.org/src/contrib/PACKAGES' But nothing happens. Is this a problem with my proxy setting since I am working behind a firewall? It seems so: > Sys.getenv("http_proxy") http_proxy

Hi all, Roger Peng and Jason Turner's suggestion with ImageMagick seem to be the simplest "dirty" way to get the problem solved. But I ran into yet another interesting but quite round-about way to solve the problem (partially). Through tcltk package, one can read in the gif image with > x <- tkcmd("image", "create", "photo", file=mypic.gif)

Hi, I am trying to use "read.pnm" from the package "pixmap" to read more than 10 thousand image files in "mydir". > file.list <- dir( "mydir", full=T) > for( i in 1:length(file.list) ) { print(i) x <- read.pnm(file.list[i]) } In the beginning it was fine. But after reading 1020 images or so, the read.pnm function seems to crash on
