How to create a panel time series plot?
I have panel data with ID=1,2,3… year=2007,2008,2009… and a factor foreign=0,1, and a variable X. I would like to create a time series plot with x-axis=year, y-axis=values of X that compares the average (=mean) development of each factor over time. As there are 2 factors, there should be two lines, one solid and one dashed.

Data Tip: You can type ?strptime into the R console to find a list of date format conversion specifications (e.g. %b = month). Type scale_x_date for a list of parameters that allow you to format dates on the x-axis. Data Tip: If you are working with a date & time class (e.g. POSIXct), you can use scale_x_datetime instead of scale_x_date.
