Re: [R] Time in ggplot2

2010-06-22 Thread Hadley Wickham
Hi Ottar, It's a bug in the code that automatically figures out the axis ticks. I have some code to fix it, but it's waiting for a release of another package. In the meantime, you can work around it by specifying where you want the breaks: ggplot(data, aes(time, PU) ) + geom_line() +

That's a bit disingenuous, Hadley. There have been reports of problems with POSIXct and ggplot2 for at least six months, particularly with values that have no time portion. You have promised a fix before, but l haven't seen it, so I convert to Date to work around the bug. Hadley Wickham

Hi Jeff, I am not aware of any problems with POSIXct and ggplot2, so I'm not sure what you're referring to. I don't ask for reproducible examples to be malicious - they make it easier for me to figure out exactly what's wrong and recommend a fix. Without a simple reproducible example, all I
