I am attempting to apply a one-dimensional PCNM using the quickPCNM function. I have a response variable ("Au"), with 2251 observations, and corresponding 'coordinates' ("time"). I know PCNM wasn't designed for time-series analysis per se but I haven't assigned the data to class "ts" so this shouldn't be any different to a one-dimensional spatial series.
require (PCNM) Au.quick.PCNM <- quickPCNM (Au, time)
After 3 attempts lasting for over 24 hours each time, R seems to get hung up, displaying only the following: 'The sites form a straight line on the map.' 'Truncation level = 0.040001' ....and this is as far as it gets. I'm running a 3GHz Pentium 4 with 2GB of RAM - not great but I would have thought adequate enough. Could it be a problem with my build? Many thanks, Martin Wilkes University of Worcester
