WeightedCells | R Documentation |

This function performs square-root of the cosine of the latitude weighting on the given array.

```
WeightedCells(data, lat, lat_dim = "lat", method = "cos", ncores = NULL)
```

`data` |
A numeric array with named dimensions, representing the data to be applied the weights. It should have at least the latitude dimension and it can have more other dimensions. |

`lat` |
A numeric vector or array with one dimension containing the latitudes (in degrees). |

`lat_dim` |
A character string indicating the name of the latitudinal dimension. The default value is 'lat'. |

`method` |
A character string indicating the type of weighting applied: 'cos' (cosine of the latitude) or 'sqrtcos' (square-root of the cosine of the latitude). The default value is 'cos'. |

`ncores` |
An integer indicating the number of cores to use for parallel computation. The default value is NULL. |

An array containing the latitude weighted data with same dimensions as parameter 'data'.

```
exp <- array(rnorm(1:30), dim = c(lat = 3, lon = 5, sdate = 2))
lat <- c(10, 15, 20)
res <- WeightedCells(data = exp, lat = lat)
```
