 Rand Wilcox has produced a set of functions for S-Plus and (IIRC) R, which
includes Theil-Sen regression.

The following url gives a pdf to the workshop that they were designed to
accompany, along with instructions on how to source and use them.


The following url is to his homepage which gives the above link plus those
to the function files themselves.

I am analyzing some climate time series data using the Mann Kendall package
and was wondering if there was a way to calculate the trend using Sen's
nonparametric estimator slope in R?

Thank you in advance,
