logLik == -Inf in gls

lagcap2 -0.0088080 0.0041099 -2.143127 0.0332
Does anyone have any suggestions of how I can get a meaningful value for
logLik? Or some other way that I can compare models.
Thankyou for your help,
Lillian.

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?
Thankyou for you help,
Lillian.

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.
Thankyou again,
Lillian.

GLS models - bootstrapping
...n.sim=100,ran.gen=beaver.gen,ran.args=beaver.args)

beaver.boot$t0
beaver.boot$t[1:10,]
Maybe there is a more elegant way for doing this. Anyway, boot.ci should
give you confidence intervals.
Let me know how you are doing.
Best, Christian

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
