plot_facet: Facet plot

In phytomosaic/grlyr: Ground Layer Estimation

Description

Scatterplot or histogram faceted by groups.

Usage

plot_facet(data, x, y, by, free = "none", type = "plot",
  qline = TRUE, ...)

Arguments

data	data.frame in long format.
x, y	name of variable in data for which values are plotted.
by	name of grouping variable in data.
free	one of c('none','x','y','xy'), defining which axes will freely vary; otherwise axes will be identical among all facets.
type	one of 'plot' or 'hist', defining which type of plot.
qline	if type = 'hist', then qline = TRUE will plot vertical lines at the 25/50/75th percentiles.
...	further arguments passed to plotting functions.

Details

Useful for disaggregating by some grouping variable, either as a bivariate scatterplot ('type = plot') or univariate histogram ('type = hist').

Value

Plots to device.

Examples

data(est)
x  <- calc_biomass(est)
fg <- summary_fg(x, eachplot=TRUE)
fg$logmass <- log10(fg$mass+1)
plot_facet(fg, 'cover', 'mass', by='fg', type='plot',
           xlab='Plot cover (%)',
           ylab=bquote('Biomass (kg' ~ha^-1*')'))
plot_facet(fg, 'logmass', by='fg', type='hist', breaks=33,
           xlab='Biomass', ylab='Frequency')
