Hi I am interested in extending mapstraction to include the UK Ordnance Survey OpenSpace API (http://openspace.ordnancesurvey.co.uk). First can I check that no-one else is working on this? Assuming not, is there any documentation that might point me in the right direction to get started, or should I just search the code for case ''google'' and insert...

...The system also supports map projections. You can do this: R> map("state",proj="merc") to draw the map on a mercator projection. I have used the USGS PROJ4.2 projection library, and so there are many projections and options available. I've also added a Great Britain Ordnance Survey grid projection to PROJ4.2, for use with maps of this area. You can also do inverse projections - plot a map with a projection, get locations with locator(), and then inverse-project them to get back to lat-long coordinates. That's all the good news. The bad news is that there's...

Is there any R package that can help me with digging out the maxima of a 1-D trajectory ? I have 975 1-D curves. They are only known as time series. That is a set of points ordered with respect to time. Some curves exhibit one only peak. Others have two peaks of different height. We wish to find the number of peaks and their position along the time axis. Apparently it's a trivial problem
