I have some spatial patterns of sardine eggs (presence /absence) over 50 years (270 surveys) and I'd like to quantify the patches and gaps to determine how many patches (i.e. spawning areas) there were before the fishery collapse (1951-1965) and during recovery (post 1985). The sampling domain runs from San Francisco to the Mexican border and out beyond the continental shelf. The grid spacing is fairly sparse (30 to 70 km), and irregular (closer nearshore than offshore)(see CalCOFI web pages if you are interested: <http://www.calcofi.org/>). I thought that SADIE <http://www.rothamsted.ac.uk/pie/sadie/SADIE_home_page_1.htm> might be useful, and am wondering if anyone has implemented this analysis method in R? I have failed to find any implementation on the R-site search, through google, or looking at the R packages browse by topic page.
