Hi Jim  

Thank you for your quick response. This worked great. I am having the same problem again. I have moved on to calculating returns from rates and want to plot returns on the y axis and again dates on the x axis. The code I am using to calculate returns is as follows: rate<-x$Rate
returns<-(diff(log(rate)))
If I do:
plot(returns, type="l") I get the graph I want however am having problems with the x axis again. Modification of the code below doesnt work as I now have one less dimension in returns. Hope I am making sense. Your help is much appreciated.

I am using the following code: plot(rate, type='l', xlab='Date', ylab='Rate', main=' to Euro rate over 5 years')This gives me the graph I want although I want to display the dates on the x axis, even if its just 2002, 2003,...2008. Attached is my data.
