I want to calculate the Spearman rank correlation for a bivariate dataset by using the tiedrank function to rank the value for both of my variables. However, Spearman rank tests require that the highest values have the lowest rank and the lowest values have the highest rank. The tiedrank function returns the highest rank for the highest values and the lowest rank for the lowest values. Is there a way to reverse the tiedrank function?

Thanks!
