I want to run Phillips-Perron test with no constant and trend in estimated
equation in urca library then how i can run it with command ur.pp()? whereas
if i want to run ADF test in urca library then there is no problem.Kindly guide

(if not, that will probably not work) and see if the workspace will load

Saved workspaces are compressed, often highly compressed.

Dear Mr. Bengtsson,
I see that there is a package exclusively for clustering data, named as
Cluster Package in R library. It has some clustering algorithms implemented.
Can you tell me how to implement the CLARA and PAM functions from that package
for my data?

My name is Michela Marignani and I'm an ecologist trying to solve a problem
linked to knight' s tour algorithm.
I need a program to create random matrices with presence/absence (i.e. 1,0
values), with defined colums and rows sums, to create null models for
statistical comparison of species
If I understand your problem properly, then your matrices have a
known number of zeros and ones in them. So you can create a
matrix with just this constraint binding via:
mat - matrix(sample(rep(0:1, c(nzeros, nones))), nr, nc)
That command first generates the appropriate number of zeros and ones
(the
Metropolis step).

Dear all,
I am calling a table (data of several years) by psql command (order by

aggregate(mydata[, c(nymphs, adults)],list(date = mydata$date)

2 09-30-1999 0.1667 0.

As far as I can see those are just character strings, and what has psql to
do with it? Some more details would have been helpful.
Your strings do not appear to be valid dates: the ISO standard is
1999-09-29 etc. So the simplest solution is to use a Standard data
