I have attempted to supply prior weights to the dataset, though this does not improve the classification greatly. Could anyone supply some

Getting all R packages
Rather than spend a tedious interactive session picking several (in fact most) of the library packages off the CRAN site one by one, it would be handy to be able to grab the lot in one go (they seem to add up to about 24MB, so it's not a huge download). Is there a way to do this? Thanks for the help. Ted. -------------------------------------------------------------------- E-Mail: (Ted

Image processing? Manipulating image data in R?
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?

Writing a tabel in LaTeX-format
I have a vague recollection of seeing a R-function that will output a table or matix in a format suitable for the tabular enviroment in LaTeX. But I cannot find it. Any hints?

repeating rows or columns within a matrix
Hello Spse I have a matrix, say 1 2 3 4 5 6 7 8 9 and I would like to expand it by repeating rows within the matrix, to get, if the repeating factor is 2, say: 123 123 456 456 789 789 (or columnwise as well) . There must be a smart way of doing that? Many thanks Juhana Vartiainen juhana.vartiainen at labour.fi -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

read.table
When I read a table (the dimnames of the table are numbers), R reads the column names as: X plus the number (X1,X2,X3,...) and the rownames as the numbers (1,2,3,...) How can I suppress this action? The code and the output: ^^^^^^^^^^^^^^^^^^^^^^^^ > r2<-read.table("h:\\matrix",header=T,dec=",",na.strings="-99") > dimnames(r2) [[1]] [1] "500"

Literature needed
Howdy! Could somebody point me to some good introductory readings about data mining and descriptive data analysis? I'm a psychologist and a couple of times I realized that some things just don't appear in psychological literature, e.g. I've never seen a box plot anywhere in psych journals so I'm not familiar with them.

S-Plus 2000 <-> R 1.0.1
Good day: Let's say that I have a data frame in S-Plus 2000 (Win98 version). I want to use the same data frame with R on another computer. Questions: 1) Can R read S-Plus data frames? Can S-Plus 2000 read R data frames? 2) How can i move the data frame between the two systems? Do I need to use dump()? Thank you.
