Statistical summary and other functions for hyperSpec

The following functions for hyperSpec objects:

• all(), any(),

• sum(), prod(),

• min(), max(),

• range(), and

• is.na()

All these functions work on the spectra matrix.

# S4 method for hyperSpec
Summary(x, ..., na.rm = FALSE)

# S4 method for hyperSpec
is.na(x)

all_wl(expression, na.rm = FALSE)

any_wl(expression, na.rm = FALSE)

Arguments

x	hyperSpec object
...	further objects
na.rm	logical indicating whether missing values should be removed
expression	expression that evaluates to a logical matrix of the same size as the spectra matrix

Value

sum, prod, min, max, and range return a numeric, all, any, and is.na a logical.

Details

all_wl() and any_wl() are shortcut function to check whether any or all intensities fulfill the condition per spectrum. na.rm behavior is like base::all() and base::any().

See also

base::Summary() for the base summary functions.

base::all.equal() and base::isTRUE()
