polarise

Convert Cartesian coordinates to Polar coordinates

Methods for fitting various extreme value distributions with parameters of
generalised additive model (GAM) form are provided. For details of distributions
see Coles, S.G. (2001) <doi:10.1007/978-1-4471-3675-0>, GAMs see Wood, S.N. (2017)
<doi:10.1201/9781315370279>, and the fitting approach see Wood, S.N., Pya, N. &
Safken, B. (2016) <doi:10.1080/01621459.2016.1180986>. Details of how evgam works
and various examples are given in Youngman, B.D. (2022) <doi:10.18637/jss.v103.i03>.
