hyperSpec (version 0.100.2)

mean_sd,numeric-method: Mean and Standard Deviation Calculate mean and standard deviation, and mean, mean \(\pm\) one standard deviation, respectively.

Description

These functions are provided for convenience.

Usage

# S4 method for numeric
mean_sd(x, na.rm = TRUE, ...)
# S4 method for matrix
mean_sd(x, na.rm = TRUE, ...)
# S4 method for hyperSpec
mean_sd(x, na.rm = TRUE, ...)
# S4 method for numeric
mean_pm_sd(x, na.rm = TRUE, ...)
# S4 method for matrix
mean_pm_sd(x, na.rm = TRUE, ...)
# S4 method for hyperSpec
mean_pm_sd(x, na.rm = TRUE, ...)
# S4 method for hyperSpec
mean(x, na.rm = TRUE, ...)
# S4 method for hyperSpec
quantile(x, probs = seq(0, 1, 0.5), na.rm = TRUE, names = "num", ...)

Value

mean_sd returns a vector with two values (mean and standard deviation) of x.

mean_sd (matrix) returns a matrix with the mean spectrum in the first row and the standard deviation in the 2nd.

mean_sd returns a hyperSpec object with the mean spectrum in the first row and the standard deviation in the 2nd.

mean_pm_sd returns a vector with 3 values: mean - 1 sd, mean, mean + 1 sd

mean_pm_sd (matrix) returns a matrix containing mean - sd, mean, and mean + sd rows.

For hyperSpec objects, mean_pm_sd returns a hyperSpec object containing mean - sd, mean, and mean + sd spectra.

For hyperSpec object, mean returns a hyperSpec object containing the mean spectrum.

For hyperSpec object, quantile returns a hyperSpec object containing the respective quantile spectra.

Arguments

x

a numeric vector

na.rm

handed to mean and sd

...

ignored (needed to make function generic)

probs

the quantiles, see quantile

names

"pretty" results in percentages (like quantile's names = TRUE), "num" results in the row names being as.character (probs) (good for ggplot2 getting the order of the quantiles right). Otherwise, no names are assigned.
