Receive "unable to load shared object RNetCDF.o" during R INSTALL of RNetCDF
On a Red Hat Linux cluster I am seeing the following after multiple
other packages were successfully installed. The error seems to suggest
that RNetCDF.o was not copied to the appropriate lib folder. The admin
user performing the install has the required privileges to perform the
install. Words of wisdom are greatly appreciated:

: plot different axis, same plot position
Dear R-users,
I am trying to make a plot in R where x and y are plotted in a regular way, but the x axis corresponds to another set of values.
For example I have x,y and T (all 29 values)
x<- c( -1.31846232, -1.04744756, -0.87034853, -0.72883370, -0.60618971, -0.49501845, -0.39128988, -0.29250120, -0.19694055, -0.10334039, -0.01069355, 0.08185470, 0.17507665, 0.26971270, 0.36651292,

Packages
I am in need of the udunits and udunits-devel packages. I know I
remember seeing the udunits package on the CD's but don't recall seeing
the udunits-devel. Looking at the rpm-pbone.net, I only found versions
avilable for FC. Would it break a bunch of stuff to install both
packages on a 4.1-i386 system ? Also looked via yum, at Dag's
repository, and mirrors, but nothing shows

enty-wise closest element
Dear R-users,
i have a simple problem maybe, but i don't see the solution. i want to
find the entry-wise closest element of an vector compared with another.
ind1<-c(1,4,10)
ind2<-c(3,5,11)
for (i in length(ind2):1)
{
print(which.min(abs(ind1-ind2[i])))
}
for ind2[3] it should be ind1[3] 10, for ind2[2] it should be ind1[2] 4
and for ind2[1] it should be ind1[1] 1. but with the

HCLUST subroutine question -- FORTRAN DO loops
Shown below is most of the FORTRAN subroutine named HCLUST.
My question concerns the DO loop labeled as '10'. What happened to its
CONTINUE statement? I will assume that after FLAG(I)=.TRUE. is executed that
control returns to DO 10 I=1,N. Am I correct?

bootstrapping lambda values from projections matrices
Dear all,
I'm working with a population projections matrix model from demographic
data. The dominant eigenvalue of the matrix is the growth rate of the
population (lambda). I would like to estimate confidence intervals for the
lambda values with bootstrap.
The function for calculating the eigenvalue I wrote like this:

similarity matrix
Hello R-users,
I've got a file with individuals as colums and the clusters where they occur
in as rows. And I wanted a similarity matrix which tells me how many times
each individual occurs with another. My eventual goal is to make
Venn-diagrams from the occurence of my individuals.
So I've this:
cluster ind1 ind2 ind3 etc.

Hi,
I'm doing robust regression with the following command
rlm(dip~ind1+ind2-1,method="M",psi=psi,maxit=1000,acc=1e-15)
now when I ask for a summary
summary(rlm(dip~ind1+ind2-1,method="M",psi=psi,maxit=1000,acc=1e-15))
I get

recursive derivative a list of polynomials
Dear list,
This is quite a specific question requiring the package orthopolynom.
This package provides a nice implementation of the Legendre
polynomials, however I need the associated Legendre polynomial which
can be readily expressed in terms of the mth order derivative of the
corresponding Legendre polynomial. (For the curious, I'm trying to
calculate spherical harmonics [*]).

pivot table help
Hello R-users,
I've got a huge table with about 20.00 rows and 50 columns. The table now
has headers as Members1, Members2 etc. My data are 8 different individuals.
And I've got a column with clusters. So each individual belongs to different
clusters and can occurs multiple times within a cluster (that's the reason
that there can be more than 8 members). I want a presence/ absence

Request: make `var` a generic
Hi all,
I am running into problems using `summary.lm` as calling `var` on a `units`
object does not retain the `units` attribute.
The units package addresses this issue for `mean` by implementing
`mean.units`:
units:::mean.units
function (x, ...)
{
.as.units(NextMethod(), units(x))
}
This is, however, not possible for `var` (as it's not a generic), which
breaks `summary.lm`:
