Eelgrass: Eelgrass Genotypes

In abd: The Analysis of Biological Data

Description

Number of shoots (shoots) surviving in each of 32 experimental plots planted with 1, 3, or 6 different genotypes of eelgrass (treatment.genotypes).

Format

A data frame with 32 observations on the following 2 variables.

genotypes

a numeric vector of the number of genotypes planted in each plot

shoots

a numeric vector of the total number of shoots in each plot

The 'mosaic' package masks several functions from core packages in order to add 
additional features.  The original behavior of these functions should not be affected by this.
