PCARaster: PCARaster - PCA of Raster files

In vijaybarve/ENMGadgets: Tools for Pre and Post Processing in ENM workflow

Description

Performs Principle Component Analysis of Raster objects and returns summary and loadings for the componetns. For interactive version check iPCARaster

Usage

PCARaster(BioStackFiles = NA, LoadingFile = NA, CompImpFile = NA,
  OPfolder = NA)

Arguments

BioStackFiles	- ESRI ASCII grid files of predictor variables
LoadingFile	- name of output file which stores loadings for components
CompImpFile	- name of output file of the PCA summaries
OPfolder	- name of output folder to save PCA component, loading and summary file

Details

Main function to generate PCA for the selected bioclimatic layer and then save the pca components in ASCII format. This function will accept the bioclimatic ASCII files. PCApca components are stored as Comp1.asc, Comp2.asc...... and so on. This function retuns the pca of the ascii data supplied to do further processing like checking for eigen values, broken stick etc.

Value

a summary of the PCA is returnd as a strcture
