R help - Nov 2006 - Look for a R Package to locate peak data point in one dimensional data set

Hi,

I am working with one array of data point.  The value of the data points
fluctuate and I tried to locate the peak point in this array.  It is like
you are going through the valleys and mountains, and I want to identify all
the mountain peak location.

I assume this is a very common problem to discover peaks and/or segregate
peak shoulders one dimensional data sets.  So is there any packages that I
can plug in to do the computation?

Thanks much in advance.

I think the Bioconductor package PROcess has functions for that.
