as.hexagons: Expand hexagon centerpoint grid into hexagon vertices

In grady/geophyttertools: Plotting tools for geophytter+ output

Description

This function expands a data frame of hexagonal tiling centerpoints into one containing hexagon vertices suitable for plotting with geom_polygon. The columns containing the x and y coordinates of the centerpoints are specified in the formula, y~x. The groupvar parameter names a new column in the output containing the hexagon id (i.e., aes(group=groupvar)).

Usage

as.hexagons(data, formula = y ~ x, groupvar = "cell")

Arguments

data	dataframe
formula	formula defining the columns with centerpoint data
groupvar	name for new column with hexagon group index

Value

a new data frame with 6*nrow(data) rows and ncol(data)+1 columns
