R help - Jan 2012 - modeling a haemodynamic response function in R

Hi,


I have time-series data and I would like to fit a 2-gamma HRF to the data
(http://en.wikibooks.org/wiki/SPM/Haemodynamic_Response_Function)
in order to get the explained variance and the maximum of the fitted data.

Is there a straightforward function for that or a package that provides
functions for this kind of procedure?


thanks!
