Hi All, I have ESRI ASCII grid format files. I want to apply principal component on those files and then save those PCA components into ASCII grid format. I used raster package to perform this operation. My steps are 1...
I use following function to generate the stack from .asc files. library(raster) MakeStack <- function(Prompt) { Mfiles = choose.files(caption=Prompt) for (i in 1: length(Mfiles)) { fl1 = raster(Mfiles[i]) if (i == 1) { stk = stack(fl1) } else { stk = stack...
Hi Michael, I generate a table of x,y and z after principal component is generated. In this case z is PCA component value and thus this is my xyz table which I want to convert to raster using rasterFromXYZ...
