Thanks.
Clara() is performing well.
I had a dataset of 7500 rows and the clustering was produced very quickly

Hi, if I understand you correctly, you would like to change the value of
all elements with current value of 3 to 9. This is how you do it:
a1 <- c(1,2,3,4,3,5)
idx <- (a1 == 3)
a1[idx] <- 9
or in one line
a1[a1 == 3] <- 9
Look at 'idx' above. It is a logical vector of the same leng

I have a few questions on formatting wireframe plots:
1. How can I remove (or at least "white-out") the border on the plot?
(I.e., the 2-d box around the whole plotting area, not the 3-d cube). I'm
willing to hack the code if necessary.
2. Is it possible to suppress plotting of all sides of t

I was asking about which R *package* and version: R itself does not
interface to any DBMS, but there are several ways to interface to PgSQL
and they are *packages* like RPgSQL, which has different versions in
different repositories (although AFAIK none are current on CRAN).

Thank you for your reply! I did try to install directly from source code.
However I got the following error information:

And which R package are you using, which version, from which repository?

Brian D. Ripley,
I've been using R on FreeBSD for several years now so I can tell you it
works fine. However I have not yet upgraded to FreeBSD 5.0 so perhaps it
has something to do with the new version. Here's something you may want
to try: Rather than using the old version of R from the FreeBSD ports
collection,

What distance metric are you using? See if clara() in cluster library
etc is more appropriate.

Dear R-help
Dear R-help list members
i would like to use R to produce clustering or partitioning of a dataset.
I am trying to use the functions:
- hierclust() of the package multiv
-pam(), agnes() and fanny() of the package cluster
But I cannot get any result because of lack of memory. Would you know any
May I suggest you learn the handy function called which().
yes.rows <- which(x[,1]==3)# Row that meets this condition
x[ yes, 2] <- x[ yes.rows, 2] * 5 # Perform the desired change for the
row that meets this condition.

I truly thank for evrybody to give me many very
good answers and suggestions.
I like to summarize the replies with their results
