Note the warning on the help page for recordPlot. If your colleague is using a

Another approach (or the start to one that you could build on) is the

Using tau = -1 is causing rq() to try and estimate all possible quantiles
and store the results. With 11253 observations this would be a formidable
feat. Try estimating the model with say tau = 1:99/100 to give a more
tractable number of estimates.

Hi, I am trying to plot the original data with the line of the model using
the predict function. I want to add SE to the graph, but not sure how to
get them out as the predict function for gls does not appear to allow for

Here is my code so far:

This is a very basic question, so please bear with me.

So far, I've got something similar to:
