Plotting shapefiles on existing maps
...;-read.shape("D://My Documents/BarentsSea.shp",dbf.data=T) (This is in mercator projection). Despite extensive searches of the help files and R site, I cannot find a way to plot the contours onto the map. Does anyone have any suggestions?

Converting shapefiles to use in contour plots
...ish to add these contours onto a map (already coded using 'maps' package) to map the sea contours with surrounding coastlines and answers to my previous question (thankyou to everyone for that) seem to suggest that using contour plot is the way to go.

GLS models - bootstrapping

Anyway, boot.ci should give you confidence intervals. Let me know how you are doing.

GLS models - bootstrapping
Hello, I am have fitted GLS models to time series data. Now I wish to bootstrap this data to produce confidence intervals for the model. However, because this is time series data, normal bootstrapping is not applicable. Secondly, 'tsboot' appears to only be useful for ar models - and does not seem to be applicable to GLS models. I have written code in R to randomly sample blocks of
