 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.

Subject: [R] Magnitude of trend in time series

Hello,

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,
Barry
