setWhereMeasured {photobiology} | R Documentation |
Set the "where.measured" attribute
Description
Method to set by reference the "where.measured"
attribute of an R
object.
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 'data.frame'
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 |
an R object |
where.measured , value |
A one row |
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, with the "where.measured"
attribute set.
Methods (by class)
-
setWhereMeasured(default)
: default -
setWhereMeasured(generic_spct)
: generic_spct -
setWhereMeasured(summary_generic_spct)
: summary_generic_spct -
setWhereMeasured(data.frame)
: data.frame -
setWhereMeasured(generic_mspct)
: generic_mspct
Note
This method alters x
itself by reference and in addition returns
x
invisibly. If x
is not an object of a supported class,
x
is not modified. If the argument to where.measured
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 with attr()
passing NULL
as argument for
parameter where.measured
unsets the attribute.
Method for collections of spectra recycles the location information
only if it is a one row data.frame
.
