setWhenMeasured: Set the "when.measured" attribute

Description

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

Usage

setWhenMeasured(x, when.measured, ...)
when_measured(x) <- value
# S3 method for default
setWhenMeasured(x, when.measured, ...)
# S3 method for generic_spct
setWhenMeasured(x, when.measured = lubridate::now(tzone = "UTC"), ...)
# S3 method for summary_generic_spct
setWhenMeasured(x, when.measured = lubridate::now(tzone = "UTC"), ...)
# S3 method for data.frame
setWhenMeasured(x, when.measured = lubridate::now(tzone = "UTC"), ...)
# S3 method for generic_mspct
setWhenMeasured(x, when.measured = lubridate::now(tzone = "UTC"), ...)

Value

x

Arguments

x

a generic_spct object

when.measured, value

POSIXct to add as attribute, or a list of POSIXct.

...

Allows use of additional arguments in methods for other classes.
