how to control ticks
Hi Jim, Yes you are right, file$time is decimal date. In the attached plot I want to replace decimal date with proper time axis so I can show month ticks. Decimal date misleads sometime while interpretation. Data varies from Jan-Dec 2009. Thanks, Yogesh

What is the structure of file$time? Is it Date/POSIXct? 'at=1:12' only works if those are the dimensions of file$time. So give us an idea of what the data is (PLEASE do read the posting guide
