Description

Spectra plotting with ggplot2

Usage

qplotmap(
  object,
  mapping = aes_string(x = "x", y = "y", fill = "spc"),
  ...,
  func = mean,
  func.args = list(),
  map.tileonly = FALSE
)

Arguments

object

hyperSpec object
mapping

see geom_tile
...

handed to geom_tile
func

function to summarize the wavelengths
func.args

arguments to func
map.tileonly

if TRUE, mapping will be handed to geom_tile instead of ggplot.

These functions are still experimental and may change substantially in future.

Note that qplotmap will currently produce the wrong scales if x or y are discrete.

Value
