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. The R help function is great when it comes to explaining

Dear R-user, I wish to know if someone is using R as concern Datamining or KDD (Knowledge Discovery in Database) and if already exists a R package specialized in this kind of analysis. I found this contributes on the R web site: [20] Diego Kuonen. Introduction au data mining avec R : vers la reconqu??te du `knowledge discovery in databases' par les statisticiens.

Does R have a bootstrap command like SPlus, or do we have to form our own code if we want to do bootstrapping in R?

I reinstalled R-1.0.0, R-1.1.1 and R-1.2.0 from scratch, and always run into the same error message: ... [Previously saved workspace restored] now

Hello all, I am currently working with rpart to classify vegetation types by spectral characteristics, and am comming up with poor classifications based on the fact that I have some vegetation types that have only 15 observations, while others have over 100. I have attempted to supply prior weights to the dataset, though this does not improve the classification greatly. Could anyone supply some

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.

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"

Hi, i have some problems to get means, but the data have got NA's which should not be replaced or delete ! tapply(data,var,mean) # makes me problem,because when one value is NA mean is NA,too. Another attempt is this, because the summary does what i want , but is not subsetable to summary[4] if i use tapply,table and the the function below gives me again all means as NA ? xmean

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

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 All, I am trying to analyse the results of a heap of samples, to determine how many samples are required to meet a defined confidence interval. I checked out the R manual for bootstrapping and re-sampling methods, but did not find anything. Are there any contributed procedures that deal with this? thanks, Matt Redding Soil Scientist Intensive Livestock Environmental Management-Research

R people, I need to know if is possible to make data mining with R. If so, is there any manual or somewhere/one to consult about that. Thank you very much Adri?n
