Scatter plot - using colour to group points?
There's also the lines() command which takes a col argument if you want to do multiple lines (I usually wind up wrapping it in a for loop though there might be something smarter) ggplot2 is great, though the learning curve is a little rough: you can get good help here but if you go down that path, there's also a dedicated ggplot2 list that's worth checking out. Glad to have you as a new useR! Michael

Thanks all for suggestions. I now have a nice plot showing the temperature of 6 different sites, each site distinguished by different coloured points, using nested ifelse. My apologies I thought I could change the type to "l" and the same arguments would be applied to line graph, with 6 different lines for each site...? I wanted to try lines as I think they might show the trends more clearly. I have just found the plottrix package manual and will try that to achieve this, and look at ggplot too. -- View this message in context: http://r.789695.n4.nabble.com/Scatter-plot-using-colour-to-group-points-tp4092794p4095079.html Sent from the R help mailing list archive at Nabble.com.
