getWhenMeasured: Get the "when.measured" attribute

Description

Function to read the "when.measured" attribute of an existing generic_spct, generic_mspct, summary_generic_spct, data.frame or a derived-class object.

Usage

getWhenMeasured(x, ...)
when_measured(x, ...)
# S3 method for default
getWhenMeasured(x, ...)
# S3 method for generic_spct
getWhenMeasured(x, as.df = FALSE, ...)
# S3 method for summary_generic_spct
getWhenMeasured(x, as.df = FALSE, ...)
# S3 method for data.frame
getWhenMeasured(x, as.df = FALSE, ...)
# S3 method for generic_mspct
getWhenMeasured(x, ..., idx = "spct.idx")

Value

POSIXct An object with date and time.

Arguments

x

...

Allows use of additional arguments in methods for other classes.

as.df

logical If TRUE return a data frame instead of a list, when the value stored in the attribute is a list.

idx

character Name of the column with the names of the members of the collection of spectra.
