Set the "where.measured" attribute
Function to set by reference the "where.measured" attribute of an existing generic_spct or an object of a class derived from generic_spct.
setWhereMeasured(x, where.measured, lat, lon, address, ...) where_measured(x) <- value ## Default S3 method: setWhereMeasured(x, where.measured, lat, lon, address, ...) ## S3 method for class 'generic_spct' setWhereMeasured(x, where.measured = NA, lat = NA, lon = NA, address = NA, ...) ## S3 method for class 'summary_generic_spct' setWhereMeasured(x, where.measured = NA, lat = NA, lon = NA, address = NA, ...) ## S3 method for class 'generic_mspct' setWhereMeasured(x, where.measured = NA, lat = NA, lon = NA, address = NA, ...)

This method alters x itself by reference and in addition
returns x invisibly. If x is not a generic_spct or an object of a class derived from
generic_spct, x is not modified. If where is not a POSIXct object
or NULL an error is triggered. A POSIXct describes an
instant in time (date plus time-of-day plus time zone). As expected
passing NULL as argument for where.measured unsets the
attribute.
Method for collections of spectra recycles the location information only if it is of length one.
