Description

GRIP 1.0 is a program that generates sets of random input parameters for sensitivity analysis of population viability analysis (PVA) models created with RAMAS Metapop 4.0. Instructions for use can be read by opening GRIP_1.r in a text editor. GRIP 1.0 is written in and run with R, a statistical and graphical system. R can be downloaded freely from the R Project for Statistical Computing
