a factor with the levels control, high, low

Details

The abundance of each species was measured as the count of the number of organisms in the sample.

Examples

data(solberg)
solbergdat <- mvabund( solberg$abund )
treatment <- solberg$x

## Create a formula for multivariate abundance data:
foo.sol <- mvformula( solbergdat ~ treatment )

## Fit a multivariate linear model:
lm.solberg <- manylm(foo.sol)
lm.solberg

Example output

Call:
manylm(formula = foo.sol)
