Hi Jim, Thanks for your email. My question was: how to change the x axis labels without changing the chart. Or is that not possible? Using your example, I added another column: sydf<-read.table(text="year1 month-day rate 1993 05-01 0.608 1994 06-01 0.622 1996 07-01 0.623 1998 08-01 0.647 2000 09-01 0.646 2002 10-01 0.625 2004 11-01 0.628 2006 12-01 0.685 2008 01-01 0.679 2010 02-01 0.595 2012 03-01 0.567 2014 04-01 0.599 2016 05-01 0.642 2018 06-01 0.685", header=TRUE)
How can I show the column "month-day" as labels on the x axis, but still have the plot showing the chart as rate based on year? I tried this: plot(sydf$year,sydf$rate,type="b", xlab="month-day",ylab="Rate") but this only changes the title of the x axis to "month-day". I want the values on the x axis to show 05-01 06-01, etc. Is that possible?

As some have noted, this is a very basic question.
