Make your plot without axes by plot(...., axes=FALSE, ...) or plot(...., xaxt="n", ...) and than see ?axis.POSIXct how to fine tune date axis with format option Regards Petr > > Hope this makes it a bit clearer. > Sarah > > ________________________________________ > From: John Kane [jrkrid...@yahoo.ca] > Sent: 28 July 2010 12:48 > To: r-help@r-project.org; Sarah Chisholm > Subject: Re: [R] Help with scatterplots in R > > I think that we need an example of what you are doing before anyone can really > answer that question. > > At the moment we don't even know how you are plotting the scatterplot. > > --- On Wed, 7/28/10, Sarah Chisholm <sarah.chisholm...@ucl.ac.uk> wrote: > > > From: Sarah Chisholm <sarah.chisholm...@ucl.ac.uk> > > Subject: [R] Help with scatterplots in R > > To: "r-help@r-project.org" <r-help@r-project.org> > > Received: Wednesday, July 28, 2010, 6:57 AM > > Hi, > > > > When I plot a scatter plot, R automatically only gives the > > years on the x-axis.
