Description

Construct a stacked list of values from a data frame containing multiple prey types. Used for creating input to convhulln.

Usage

Arguments

frame

A data frame containing a list of isotope values for multiple organisms. If there are d isotope values and s organisms, then the frame is assumed to contain ds columns, where for any 1 ≤q i ≤q s-1 the columns di to d(i+1)-1 contain the isotope measurements for the ith organism. For each organism, the isotopes (columns) must be in the same order.

Value

A m \times d matrix, where m is the total number of isotopic measurements (over all organisms) and d is the number of isotopes.
