tapply and NA value
Hi,
I'm writing for a little help.
I have a dataframe with same NA value and I'd like to obtain the means of the
value of a coloumn grouped by the levels of a factor coloumn of the datframe.
I'm using the function "tapply" but I see that if only a NA value is present
the result is NA.
There is an option to have the correct result or I must use an other function?

bar charts
Hi,
I'd like plot a bar graphic of a array.
I'd like to have the values of the single columns as juxtaposed bars (like in
"barplot" with beside=TRUE) and I'd like to have the values of the single
columns expressed like percentage of the sum of the coloumn.
In this way all the bars are composed by the sum of the percentage of the
values of a coloumn (with different colors)

pr[in]comp: predict single observation when data has colnames (PR#8324)

seem to have been changed in R-devel or R-patched.
If M is a matrix with coloumn names, and
mod <- prcomp(M) # or princomp
then predicting a single observation (row) with predict() gives the

Classifying boolean values
Hi to all, I'm new to this forum and new to R. I have to build a tree
classifier that has boolean values as response.

Needed: Understading runif() output :-)
Dear all,
I have been trying to understand what runif() is telling me.
I am generating lots of numbers (billions and billions (wow, I''ve dreamed
about saying that for many years... :-) ), for a distribution that has the
following quantile function:
1 / (2 * sqrt(1 - p))
(that is, the distribution has a lower cutoff)
As you can imagine, this has rather heavy upper tail. I was

Package GSS for interpolation in more than 2D?
Dear all,

myself the last time, but eventually ended up doing it in MATLAB. I tried

R (S) code, so I failed that too, mainly because I could only get one

matrix of bins with different length
Dear users,
please help to define the following data structure:
I would like to have a matrix, where every element is a container of
different size , containing real numbers. The containers (bins) are
addressed by an index pair [i,j] (i is number of corresponding row of
the matrix, j is the coloumn of the matrix). The containers are
initially empty, I would like to fill them
