Extracts meteorological data from an object.

1 2	extractpointdates(points, dates = NULL, verbose=FALSE) extractgridpoints(griddata, points)

`points`	For function `extractpointdates()`, an object of class `SpatialPointsMeteorology`. Alternatively, an object of class `SpatialPointsDataFrame-class` containing the meta data (columns `dir`, `filename` and possibly `format`) of meteorological files that will be sequentially read from the disk. For function `extractgridpoints()`, an object of class `SpatialPoints`.
`dates`	A vector of `Date` with a (subset) of dates to be extracted. If `NULL` all dates will be returned.
`griddata`	An object of class `SpatialGridMeteorology-class` or `SpatialPixelsMeteorology-class` with the meteorological data for a full grid or a subset of grid cells, respectively. Alternatively, a `data.frame` containing the meta data (columns `dir` and `filename`) of grid/pixels meteorological files that will be sequentially read from the disk.
`verbose`	Boolean flag to print process information.

Function extractpoints is deprecated, because its functionality can be achieved using subsetting of spatial classes SpatialGridMeteorology and SpatialPixelsMeteorology.

Function extractpointdates(), returns a list with the same length as dates. Each element of the list is an object of class SpatialPointsDataFrame with the meteorological data for all the points (in rows) and variables (in columns). Function extractgridpoints() returns an object of class SpatialPointsMeteorology.
