Hi Listers, I have been trying to run spatial analyses on my fish community dataset but I am still running into errors that I cannot decipher?
My fish dataset has 114 species(variables) x 45 sites My spatial dataset has the Lat and Long values for each site, converted to cartesian coordinates > fish <- read.table(file.choose())> latlong <- read.table(file.choose()) > > fish.h <- decostand (fish, "hellinger")> fish.PCNM.quick <- > quickPCNM(fish.h,latlong) Truncation level = 639.5348 Time to compute PCNMs = 0.820000 sec Error in if (temp2.test[1, 5] <= alpha) { : argument is of length zeroTiming stopped at: 1.06 0.05 1.19 Any advice appreciated.
