Description Usage Arguments Value Author(s)
Simulate species abundance data according to stated approach or following a particular methodology.
1 2 |
n |
numeric; the number of samples/sites. |
m |
numeric, the number of species/variables. |
x |
numeric; values for the environmental gradient. Can be missing, in which case suitbale values are generated. See Details. |
gl |
numeric; gradient length in arbitrary units. The default is 4 units with gradient values ranging from -2 to 2. |
randx |
logical; should locations along the gradient
( |
tol |
numeric; the species tolerances. Can be a
vector of length |
tau |
numeric; constant that ensures some of the optima are located beyond the observed gradient end points. |
randm |
logical; should species optima along the gradient be located randomly or equally-spaced? |
... |
arguments passed on to the functions corresponding to the method used. |
method |
character; one of the available model choices. |
a matrix of n
rows and m
columns containing
the simulated species abundance data.
