D.designdata {secr}R Documentation

Construct Density Design Data

Description

Internal function used by secr.fit, confint.secr, and score.test.

Usage

D.designdata (mask, Dmodel, grps, sessionlevels, sessioncov = NULL)

Arguments

mask mask object.
Dmodel formula for density model
grps vector of group names
sessionlevels vector of character values for session names
sessioncov optional dataframe of values of session-specific covariate(s).

Details

This is an internal secr function that you are unlikely ever to use. Unlike secr.design.MS, this function does not call model.matrix.

Value

Dataframe with one row for each combination of mask point, group and session. The dataframe has an attribute 'dimD' that gives the relevant dimensions: attr(dframe, 'dimD') = c(nmask, ngrp, R), where nmask is the number of mask points, ngrp is the number of groups, and R is the number of sessions. Columns correspond to predictor variables in Dmodel.
