The function spatially aggregates using a function (for example, mean) all the grid points within the borders defined by a shapefile. The function provides some shapefiles for Europe.

1 2	get_ts_from_shp(obj, weight_matrix = NULL, aggregate_function = "mean", shapefile = "NUTS0", path_to_shapefile = NULL, cos_weighted = TRUE)

`obj`	A gridded object: a grid structure from Climate4R functions or a `list` with `lat`, `lon` and `data` fields. See Details section for further details.
`weight_matrix`	A matrix to be used as weight when aggregating
`aggregate_function`	The function to be used to aggregate the grid points. Options are: `mean` and `sum`
`shapefile`	The shapefile to be used to aggregate the grid points.
`cos_weighted`	Define if the grid points will be weighted according the cosine of the latitude

Details The obj can be: 1. a list with three mandatory fields: lat with the latitude values, lon with the longitude and data with the gridded field consistent with the coordinates; 2. a grid structure as in the Climate4R bundle (http://www.meteo.unican.es/climate4R), for example from loadeR package.

The shapefiles available are the following:
