why r is bicubic interpolation what is the plot of temperature in r interpolation between spatial coordinates what does bicubic interpolation do what is the plot used in r for interpolating what is the interpolated data r r do bicubic interpolation does r interpolate spatial coordinates which package does a bicubic interpolation need r how to do bicubic interpolation does r interpolate xyz interpolation of spatial coordinates in the data set how to do bicubic interpolating in r what package does the bilinear interpolation in r need? what is the difference between bicubic and bilinear interpolation. what is bicubic and linear interpolation in r what is bicubic interpolation what is the purpose of a bicubic interpolation what is a bicubic interpolation in r why is the interval in r bicubic or bilinear
