I am working with a circular data ( wind direction ) and i have problem in transforming the circular variable into linear variable. I have found an equation that can be used to convert the circular variable into linear variable which is included in this paper *" ARMA based approaches for forecasting the tuple of wind speed and direction". *The equation is called as the inverse of a link function and i have attached the summery of it.T herefore,Please, if you have an idea of how to conduct it in R programming or if you have another method for transformation, let me know it. Your cooperation is highly appreciated.
