This R interpolated polar contour plot question is an excellent source for interpolated polar contour plots in R. Unfortunately, as explained in the this question, the PolarImageInterpolate function in earlier post has some bugs in it. My question is, is there a modified version of the function or a package or any other (ggpot?) way to do interpolated polar contour plots in R?
Here is a sample plot I made using the PolarImageInterpolate function. There are unusual values at the centre. It seems something is not right with the interpolation? Since akima interpolation does not allow NA`s in data, I removed them using complete.cases. Is there a better option to manage NA's in interpolation?
inp <- read_csv("test.csv")
inp <- inp[complete.cases(inp),]
y = inp$Height * cos(inp$Theta)
x = inp$Height * sin(inp$Theta)
z = inp$Value
PolarImageInterpolate(x, y, z, points = F)
Data is here Any help would be appreciated.
