function for cumulative occurrence of elements
Hello,
I have a data set with 9700 records, and 7 parameters.
The data were collected for a survey of forest communities. Sample plots
(1009) and species (139) are included in this data set. I need to determine
how species are accumulated as new plots are considered. Basically, I want
to develop a species area curve.
I've included the first 20 records from the data set. Point

Can I index a dataframe with a reference from/to a second dataframe?
Hello,
I am unable to figure out how to code a new column in a data frame based
on an existing column that matches a column in a reference data frame,
in a relational-db fashion. I would like this to maintain a minimum set
of reference tables that may be reused over several similar datasets.
Specifically, I have two data frames as listed below, 'Bos' and 'tree.'

Cluster prediction from factor/numeric datasets
Hi all,
I have a dataset with numeric and factor columns of data which I developed a
Gower Dissimilarity Matrix for (Daisy) and used Agglomerative Nesting
(Agnes) to develop 20 clusters.
I would like to use the 20 clusters to determine cluster membership for a
new dataset (using predict) but cannot find a way to do this (no way to
"predict" in the cluster package).

linear lists, creation, insertion, deletion, traversal *someone?*
Hi,
In a second try I will ask this list to give me some useful pointers.
Linear lists, as described e.g. by N.Wirth in "Algorithms and Data
Structures", seem not to be implemented in S/R, although in lisp we have
cons, car, cdr.
Nevertheless I want to implement an algorithm using such linear lists,
porting a trusted program to R (S). I need:

Maple and R
Hi R-users,
Can Maple function be exported to R?
I have a jacobian matrix (4X4)?from maple in algebraic form which involve modified Bessel function of the first kind.
I just wonder whether we can use algebraic form into R before the value of the parameters can be estimated.
Thank you so much for your attention and help.

[LLVMdev] make lldb work
Sorry if asked before.
I'm new to LLDB, try to use it according to the lldb project site. I write
some very simple code like:
#include <stdio.h>
int main(int argc, char **argv)
{
int counter = 0;
while ( counter < 10 )
counter++;
printf("counter: %d\n", counter);
return 0;

elements that appear only once
Hi.
I have a factor and I want to extract just those elements that appear
exactly once.
How to do this?
Toy example follows.

("beech",4)))
> a
[1] oak oak oak oak oak ash elm beech beech beech beech

Wine and Maple 6
Hello list
I have installed Maple 6 with no problems. It even put a shortcut on
my Kubuntu Dapper Desktop but when I run Maple, I could see the splash
screen then everything disappears. I don't know if this means that
Maple 6 crashes. Any idea of troubleshooting?

X-Axis Problem with Multhist Plot
I am creating a side-by-side histogram using "multhist" of PLOTRIX.
However, I can't seem to control the X-axis.
It yields the following X points in the axis:
1 3 5 7 9 13 17 21 25 29 33
with uneven spacing between x-ticks (see attached file).
Especially I want to create a bar for every x-axis (1,2,3,4...36),
now not every x-axis has a bar.
Is there a way to alter my following

symbolic math
Hi all!
Does anyone knows if it exists a "symbolic math" package in R, that allows to compute derivatives, integrals, etc.?
Does exist a freeware version of Maple?

R numerical integration
Hi all,
Is there any other packages to do numerical integration other than the
default 'integrate'?
Basically, I am integrating:
integrate(function(x) dnorm(x,mu,sigma)/(1+exp(-x)),-Inf,Inf)$value
The integration is ok provided sigma is >0.
However, when mu=-1.645074 and sigma=17535.26
It stopped working. On the other hand, Maple gives me a value of

Password changes and syncing passwords with Linux accounts
Hi
I'm experiencing some odd behaviour when trying to change passwords. I

I change a password (either from a Win10 Pro client, or using smbpasswd
on the machine itself) it all reports that things have worked. I can
then login to Samba using the new password.

Taking Integral and Optimization using Integrate, Optim and maxNR
Dear All, Hello!
I have some questoins in R programming as follows:
Question 1- How to take the integral of this function with respect to y, such that x would appear in the output after taking integral.
f(x,y)=(0.1766*exp(-exp(y+lnx))*-exp(y+lnx))/(1-exp(-exp(y+lnx))) y in (-6.907,-1.246)
It is doable in maple but not in R. At least I could not find the way.

problem with the precision of numbers
Hi All,
I was wodering if it is possible to increase the precision using R. I ran

Any idea how to fix this problem? thanks for your help

for(i in 0:k){
s=s+((-1)^i)*3456*(1+i*1/2000)^3000

[LLVMdev] make lldb work
Hi,
I notice you're running a 32-bit program; are you also on a 32-bit host, or do you have a 64-bit OS installed? We don't generally test on 32-bit hosts, so it's possible you found a new bug. In addition, there are some known bugs with debugging 32-bit programs (even on 64-bit hosts) which will we hopefully be resolving soon.
Nonetheless, I was unable to reproduce the behaviour you
