Function to access either species or site scores for specified axes
in some ordination methods. The
scores function is generic in
vegan, and vegan ordination functions have their own
scores functions that are documented separately with the
method (see e.g.
help file documents the default
scores method that is only
used for non-vegan ordination objects.
An ordination result.
Ordination axes. If missing, default method returns all axes.
Partial match to access scores for
Other parameters (unused).
scores is a generic method in vegan. Several
vegan functions have their own
scores methods with their
own defaults and with some new arguments. This help page describes
only the default method. For other methods, see, e.g.,
All vegan ordination functions should have a
method which should be used to extract the scores instead of
directly accessing them. Scaling and transformation of scores should
also happen in the
scores function. If the
function is available, the results can be plotted using
ordixyplot etc., and the
ordination results can be compared in
scores.default function is used to extract scores from
non-vegan ordination results. Many standard ordination
methods of libraries do not have a specific
class, and no
specific method can be written for them. However,
scores.default guesses where some commonly used functions
keep their site scores and possible species scores.
x is a matrix,
scores.default returns the chosen
columns of that matrix, ignoring whether species or sites were
requested (do not regard this as a bug but as a feature, please).
Currently the function seems to work at least for
princomp and some ade4 objects.
It may work in other cases or fail mysteriously.
The function returns a matrix of scores.
scores functions include (but are not limited to)
scores.pcnm. These have somewhat different interface
scores.cca in particular – but all work with
display="sites" and return a matrix. However, they
may also return a list of matrices, and some other
methods will have quite different arguments.
