setWhereMeasured {photobiology}

R Documentation

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, ...)

## Default S3 method:
setWhereMeasured(x, where.measured, lat, lon, ...)

## S3 method for class 'generic_spct'
setWhereMeasured(x, where.measured = NA, lat = NA,
  lon = NA, ...)

## S3 method for class 'summary_generic_spct'
setWhereMeasured(x, where.measured = NA,
  lat = NA, lon = NA, ...)

## S3 method for class 'generic_mspct'
setWhereMeasured(x, where.measured = NA, lat = NA,
  lon = NA, ...)

Arguments

`x`	a generic_spct object
`where.measured`	A one row data.frame such as returned by function `geocode` from package 'ggmap' for a location search.
`lat`	numeric Latitude in decimal degrees North
`lon`	numeric Longitude in decimal degrees West
`...`	Allows use of additional arguments in methods for other classes.

Value

Methods (by class)

default: default
generic_spct: generic_spct
summary_generic_spct: summary_generic_spct
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).

Method for collections of spectra recycles the location information only if it is of length one.
