Hi Maria,
The "plot.gam" function doesn't use the "col" argument for lines, but
does change the color of points in the second example on the help

get what you want.

Agh. I've argued elsewhere that the default behaviour should be to

the missing values, even if that simply be by changing the argument.

I think you might be bit embarrassed because it seems pretty obvious once you

Hi,
That eir$date might be a factor is irrelevant. There is an as.Date() method for
factors, which does the factor to character coercion internally and then calls
as.Date.character() on the result.
Using the example data below:

You could try with the brick function from the raster package.
