Build a convex hull of the data in a data frame using
convhulln
.

|
inputframe |
A data frame, containing isotopic measurements in data frames
imported from files using |
Use the convhulln
package to build a convex hull of the
isotopic measurements given by the input data frame. The data frame is
assumed to have the measurements presented one per row. If there are
multiple species present in the data frame, they must be added as
extra columns, and the order of the columns for each species must be
the same.
Return a m \times d+1 matrix [A|b] representing the convex hull of the system of equations Ax ≤q -b.
