Dear Stephen,  I reply you inline:

There were a bunch of blank lines in 
this area.  Maybe you put your script 
here in a picture or something which 
disappeared somewhere in the guts of the 
stat.ethz.ch mailfilter.

I came from python to R some years ago, 
and it is easier I think, if you spend 
some time on it.

Good, now provide line 11.

| | 27.

You can specify linetype as an argument 
to ggplot2::aes instead of color.  
Perhaps try this, if it is what you did.  
This should also be easy in normal plot, 
see ?par.

| | The date in the title of the plot , 
| | line 33, is the max value of the 
| | date in in line 14 and I would like 
| | to use that rather than edit the 
| | Script every time the date changes.
| 
| 2. Re: max of dates.
| 
|  max(as.Date(c("1976-04-07","1982-02-22")))
| [1] "1982-02-22"
| 
| You seem to be asking basic questions 
| that indicate a need to spend some 
| time with R tutorials, in this case S3 
| methods and dates. See ?"date-time" 
| for a terse but dense explanation; 
| numerous web tutorials are available 
| that are more suitable for most of us 
| learning new R or R package features.

Best,
Rasmus
