The functions

all, any,

sum, prod,

min, max,

range, and

is.na

for hyperSpec objects.

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 behaviour is like base::all() and base::any().

See also

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

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