R: Site statistics of 'nodiv' data objects

sitestat {nodiv}

R Documentation

Site statistics of `nodiv` data objects

Description

Adds, plots or reads site statistics from objects in the nodiv package

Usage

add_sitestat(distrib_data, site_stat, site = NULL)
plot_sitestat(distrib_data, x, shape = NULL, type = c("auto",
                 "points", "grid"), ...)
sitestat(distrib_data, statname = NULL, site = NULL)

Arguments

`distrib_data`	An object of type `distrib_data`, `nodiv_data` or `nodiv_result`
`site_stat`	A site statistic, such as species richness or mean temperature. This can be a vector or a data.frame. If `site` is not specified, the function tries to match `site_stat` to the site names of the `distrib_data` object. The function looks for vector names, rownames, or variables in the data.frame that match the site names. If sitenames are absent and the number of sitestats match, the sitestat is assumed to be in the correct order.
`site`	A character or numeric variable specifying the sites in which to enter or read sitestat
`statname`	The name of a sitestatistic in the `distrib_data` object. If statname is not given, a list of names of sitestatistics is given
`x`	A variable to plot on sites, can either be a numeric variable, or the name of a sitestatistic in the `distrib_data` object
`shape`	A shape file giving a map to use as a background for the plot
`type`	A character vector describing the type of data
`...`	Further arguments to the plotting function

Value

add_sitestat returns the object with the new sitestat inside. sitestat returns the named sitestatistic.
