join-scidbst: Joins the attributes of x and y

In flahn/scidbst: Spatio Temporal Extension for SciDB (scidbst)

Description

This function executes a join operation on two scidbst arrays, where all attributes of x and y are joined.

Usage

## S4 method for signature 'scidbst,scidbst'
join(x, y, storeTemp = FALSE, name, raf = "avg")

Arguments

x	scidbst object
y	scidbst object
storeTemp	logical whether or not some arrays are stored temporarily during the operation
name	The name of the joined output array (required if storeTemp==TRUE)
raf	the aggregation function to be applied during the spatial regrid

Details

At this point the join operation works spatial arrays only (this will be extended in the future). As a merge strategy the array with the lower resolution will be choosen as the target array. The array with the higher resolution will be regridded into the target array structure, so that cells can be merged by transfering the coordinates into the target arrays dimension indices.

Value

scidbst object with a combined object
