Hi, I am trying to run the spatial empirical orthogonal function on a raster stack using eof function in spacetime 1.2-1 package.
My raster stack is > stk class : RasterStack dimensions : 2423, 2470, 5984810, 690 (nrow, ncol, ncell, nlayers) resolution : 499.9339, 499.9718 (x, y) extent : -85163.44, 1149673, 5656775, 6868207 (xmin, xmax, ymin, ymax) coord. ref. : NA names : X2001.01.01, X2001.01.09, X2001.01.17, X2001.01.25, X2001.02.02, X2001.02.10, X2001.02.18, X2001.02.26, X2001.03.06, X2001.03.14, X2001.03.22, X2001.03.30, X2001.04.07, X2001.04.15, X2001.04.23, ... min values : 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ... max values : 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, ... >object.size(stk) 8699416 bytes The size of raster stack is ~8 mb but when I try to convert to STFDF it become several GBs until I receive error about memory. My system is sysname release version machine "Windows" ">= 8 x64" "build 9200" "x86-64" >memory.limit() [1] 32659 My R version is "R version 3.5.0 (2018-04-23)" I would appreciate any advise on possible solutions. Thank you. Shiva [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
