facet_wl: [!] Control facetting parameters in 'ggplot' of 'hyperSpec'...

In GegznaV/spPlot: Plotting and Helper Functions for `hyperSpec`, `ggplot2` and `plotly`

Description

Control facetting parameters in plot made with function ggplot of hyperSpec (ggplot.hyperSpec method) in which parameter wl.range is explicitly specified.

Usage

facet_wl(rows = ".", space = "free", scales = "free", ...)

Arguments

rows	Name of factor variable (quoted string) to be used for making rows of facets. The dot "." (default) is used to indicate that there should be no faceting on this dimension.
space	If "fixed", the default, all panels have the same size. If "free_y" their height will be proportional to the length of the y scale; if "free_x" their width will be proportional to the length of the x scale; or if "free" both height and width will vary. This setting has no effect unless the appropriate scales also vary.
scales	Are scales shared across all facets (the default, "fixed"), or do they vary across rows ("free_x"), columns ("free_y"), or both rows and columns ("free")?
...	Further parameters to be passed to facet_grid.

Details

This function is a wrapper for facet_grid and facet_grid(.~.wl.range) can be used instead of facet_wl(".").

Value

Updated ggplot2 object of class ggplot.

Examples

library(spPlot)

p <- ggplot(Spectra2, wl.range = c(min ~ 350, 500~600)) +
     geom_line(aes(color = gr))

p
p + facet_wl(space = "fixed")
p + facet_wl("class")
p + facet_wl("gr")

# Alternative to `facet_wl()` is:
p + facet_grid(. ~ .wl.range, scales = "free")

## Not run: 
# If `wl.range` is not specified, ERROR message is displayed:
p2 <- ggplot(Spectra2) + geom_line(aes(color = gr))
p2 + facet_wl()

## End(Not run)
