arcStats(product, collection=NULL, extent="global", begin="2000.01.01",
 end=format(Sys.time(),'%Y.%m.%d'), asMap=TRUE, outName=NULL,...)

Arguments

product

Character. See ?getProduct. MODIS grid product to be checked. For 'MODIS TERRA Vegetation Indices at 250 m ground resolution' use: MOD13Q1. For vegetation indices from TERRA and AQUA use M.D13Q1. Run getProduct() for an overview of supported products.

collection

Character or integer. Refers to the MODIS product collection-version. Often '005', but see MODIS pages or run ?getCollection for more information.

extent

deafult is 'global'. Additionally see the argument 'extent' in ?getTile or for interactive selection use: 'extent=getTile()'.

begin

Character. Begin date of MODIS time series. See: ?transDate

end

Character. Default is 'Today' expressed in a function. End date of MODIS time series. See: ?transDate

asMap

TRUE, FALSE or "both". Indicates if the output is a 'png' a 'csv' or 'both' of them.

outName

Character. Default is the 'product.collection.YYYYMMDDHHMMSS.png/csv' of the function call or if applicable 'product.collection.extent.YYYYMMDDHHMMSS.png/csv'

...

Any relevant arguments in MODISoptions(). Most important 'outProj' and 'outDirPath'

Value

An invisible NULL (provably this will change to a matrix like object similar to the '*.csv' output. If 'asMap'= TRUE a 'table.csv' and a 'image.png' file(s) in 'outDirPath' see MODISoptions().
