rpart unbalanced data
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

tabulate means & NA
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 ?

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.

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?

spatial library
Hi everybody,
I want to download the spatial library but I don't find it at the CRAN
list package. Where can I find the package ?
I have to download it to use the function correlogram.
Thanks in advance,
Paola.

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

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)

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. 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

kind of analysis.

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.
