Arguments

`x`	dimensions (e.g. lat, lon, depth, section distance, time, etc)
`y`	dimensions (e.g. lat, lon, depth, section distance, time, etc)
`z`	signal to be gridded (e.g. T, S, ...)
`gridder`	A function to perform gridding, options gridIDW (default: inverse distance), gridNN (nearest neighbor), gridNNI (natural neighbor) or gridKrige (Krigging)
`xlim`	Limits of the gridding. These are the bounds of the new x-y grid. Default: NULL will set it based on the data + 10 \item ylimLimits of the gridding. These are the bounds of the new x-y grid. Default: NULL will set it based on the data + 10 \item x.factorThe relative scale difference between x and y, used to calculate distances. Take into account actual scale AND the relevent scaling of the system (vertical distance tends to be more important than horizontal distance). \item y.factorThe relative scale difference between x and y, used to calculate distances. Take into account actual scale AND the relevent scaling of the system (vertical distance tends to be more important than horizontal distance). \item x.scaleThe step size in the new x-y grid. By default the scale is set to generate a grid that is 50x50. \item y.scaleThe step size in the new x-y grid. By default the scale is set to generate a grid that is 50x50. \item uncertainty= 0: Scaling applied to the distance from the cener of a grid cell to a vertex, used to add a base-line distance to all measurements. 0 = no minimum, 1 = minimum = to half a grid cell. \item nxThe number of splits to make in the x direction (defaults to 50). Used only if x.scale is not set. \item nyThe number of splits to make in the y direction (defaults to 50). Used only if y.scale is not set. \item projA gdal projection string such as from make.proj() function. Used to redistribute grid over non-euclidean surfaces like maps. \item field.nameSets the name of the new interpolated field. By default the name is 'z1' Build Section Thomas Bryce Kelly Gridding
