R: Set the "where.measured" attribute

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

x

### 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.
