Fetches gridded data

fcGrid(variable, latitudeFrom, latitudeTo, latitudeBy, longitudeFrom,
  longitudeTo, longitudeBy, firstYear = 1961, lastYear = 1990,
  firstDay = 1, lastDay = 365, startHour = 0, stopHour = 24,
  url = "http://fetchclimate2.cloudapp.net/", dataSets = "ANY",
  reproduceFor = "NOW", verbose = F)

`variable`	An identifier of the variable to fetch. To get the list of available variables use 'fcVariables()' function or see "Available data" section of documentaion
`latitudeFrom`	A numeric scalar. The lower latitude bound of the spatial grid
`latitudeTo`	A numeric scalar. The upper latitude bound of the spatial grid
`latitudeBy`	A numeric scalar. The step of the grid along latitudes
`longitudeFrom`	A numeric scalar. The lower longitude bound of the spatial grid
`longitudeTo`	A numeric scalar. The upper longitude bound of the spatial grid
`longitudeBy`	A numeric scalar. The step of the grid along longitudes.
`firstYear`	A numeric scalar. Temporal coverage definition: The lower bound of years over which the averaging is performed
`lastYear`	A numeric scalar. Temporal coverage definition: The upper bound of years over which the averaging is performed
`firstDay`	A numeric scalar. Temporal coverage definition: The lower bound of the days interval within each year over which the averaging is performed
`lastDay`	A numeric scalar. Temporal coverage definition: The upper bound of the days interval within each year over which the averaging is performed
`startHour`	A numeric scalar. Temporal coverage definition: The lower bound of the hours interval within each day over which the averaging is performed
`stopHour`	A numeric scalar. Temporal coverage definition: The upper bound of the hours interval within each day over which the averaging is performed
`url`	The URL of the service to query the data from
`dataSets`	A character vector. An identifier of the data set to fetch the data from. The special value "ANY" enables data stitching from all available data sets.
`reproduceFor`	A character scalar. A string containing the time for which the result must correspond. The format is "YYYY-MM-DD". The special value "NOW" fetch the data using the latest FetchClimate configuration available.
`verbose`	A logical scalar. If set to TRUE the method outputs its actions verbosely

Type: SpatialPixelsDataFrame (from sp package) Contains a grid definition the following fields: values, sd, provenance

#Fetching average potential evapotransiration for the upper part of Africa continent
#for Januries 2000-2010
#With 1 degree grid resolution
