Hi Steven, A basic plot can be displayed like this: sydf<-read.table(text="year rate 1993 0.608 1994 0.622 1996 0.623 1998 0.647 2000 0.646 2002 0.625 2004 0.628 2006 0.685 2008 0.679 2010 0.595 2012 0.567 2014 0.599 2016 0.642 2018 0.685", header=TRUE) plot(sydf$year,sydf$rate,type="b", xlab="Year",ylab="Rate")
When you add more years and rates to the data frame, the axes will change to include the years and rates outside the ones in your example. As some have noted, this is a very basic question.
