Set the "where.measured" attribute
Description
Function to set by reference the "where.measured" attribute of an existing generic_spct or an object of a class derived from generic_spct.
Usage
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, ...)
Arguments
x |
a generic_spct object |
where.measured, value |
A one row data.frame such as returned by
function |
lat |
numeric Latitude in decimal degrees North |
lon |
numeric Longitude in decimal degrees West |
address |
character Human readable address |
... |
Allows use of additional arguments in methods for other classes. |
Value
x
Methods (by class)
-
setWhereMeasured(default): default -
setWhereMeasured(generic_spct): generic_spct -
setWhereMeasured(summary_generic_spct): summary_generic_spct -
setWhereMeasured(generic_mspct): generic_mspct
Note
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.
