GraspeR - Restricting the data within limits
grasp.limits(gr.Yi, sX, npast, lim)
gr.Yi |
Selected responses to be used in the form of a vector with column numbers |
sX |
Selected predictors to limit from |
npast |
Number of 0 observations kept on each side of the last presence |
lim |
Limits type generaly "and" |
The grasp.limits function is optional. It restricts the data within limits defined for selected response variables by keeping a given number of 0 observations on each side of the last presence along selected predictors.
You have to call grasp.limits before calling other functions in case you want to apply limits to all the other computations.
The function can be accessed through grasp.GUI
() in menu Edit / Set limits...
