qplot_spRangeMedian: [!] Plot Median and range of spectroscopic data intensities

In GegznaV/spHelper: Extension of Package `hyperSpec` and Various Convenience Functions

[!] Plot Median and range of spectroscopic data intensities

Description

Plot range of y axis values (usually intensities) of spectroscopic data between selected percentilles.
Function qplot_spRange() returns whole ggplot and function layer_spRange() returns a layer which can be added to a ggplot.

Usage

qplot_spRangeMedian(
  sp,
  by = NULL,
  percent = NULL,
  probs = NULL,
  palette = hyGet_palette(sp),
  ...,
  lwd_median = 1,
  legend_title = by,
  alpha = 0.2,
  add = FALSE,
  name_if_by_is_NULL = "All Data"
)

Arguments

sp	hyperSpec object.
by	A vector (factor variable) with indicated groups for each case: either variable name inside the object sp, or a vector of length nrow(sp).
percent	Numeric value between 0 and 100 that indicates percentage of samples nearest to median be plotted as a ribbon.
probs	verctor of size 2 with values between 0 and 1 that indicates probabilities at which percentiles should be plotted.
...	further arguments to geom_ribon.
legend_title	(character|NULL) The title for legend.
alpha	(numeric from 0 to 1) transperency.
add	(logical) add plot to an existing ggplot object?

Value

A ggplot object. More details in package ggplot2.

library(spHelper)
library(spPlot)

qplot_spRangeMedian(Spectra2)
qplot_spRangeMedian(Spectra2, "gr")

# Both lines below gives identical plots with different default titles:
qplot_spRangeMedian(Spectra2, "gr", percent = 50)
qplot_spRangeMedian(Spectra2, "gr", probs = c(.25, .75))
