Get the "when.measured" attribute
Description
Function to read the "when.measured" attribute of an existing generic_spct or a generic_mspct.
Usage
getWhenMeasured(x, ...)
when_measured(x, ...)
## Default S3 method:
getWhenMeasured(x, ...)
## S3 method for class 'generic_spct'
getWhenMeasured(x, ...)
## S3 method for class 'summary_generic_spct'
getWhenMeasured(x, ...)
## S3 method for class 'generic_mspct'
getWhenMeasured(x, ..., idx = "spct.idx")
Arguments
x |
a generic_spct object |
... |
Allows use of additional arguments in methods for other classes. |
idx |
character Name of the column with the names of the members of the collection of spectra. |
Value
POSIXct An object with date and time.
Methods (by class)
-
getWhenMeasured(default): default -
getWhenMeasured(generic_spct): generic_spct -
getWhenMeasured(summary_generic_spct): summary_generic_spct -
getWhenMeasured(generic_mspct): generic_mspct
Note
If x is not a generic_spct or an object of a derived class
NA is returned.
The method for collections of spectra returns the a tibble with the correct times in TZ = "UTC".
