R code for inverse distance to a power

[sudheesh pai]

Hi,

I am looking for an R code to replace the inverse distance to a power
algorithm in QGIS, which has the input as point shape file. the parameters
of algorithm are radius 1 (R1), radius 2 (R2) and the z parameter.
Also, my CRS is 3006 which means that i have to specify R1 and R2 in
meters.

If some one has an example, kindly let me know.

Thank you

Sounds like you are talking about Inverse Distance Weighted functions
(IDW). Yes the gstat package has a function for that.

Example:

Enjoy,
