...d also be happy if I could do this with a cloud plot, but I can't get the colors to plot correctly. cloud(flow~day*year, data=flow.dat, shade=T, groups=grp, col.group=c("#FF3030","#43CD80","#1E90FF"), pch=20) Any help is much appreciated!

Hi All, I have a data set of daily measurements of river flow. I would like to create a "ts" object from this data. Here's a sample data set: date <- as.Date(c(1:300), format="%Y") year=as.numeric(format(date, format = "%Y")) month=as.numeric(format(date, format = "%m")) julianday=as.numeric(format(date, format = "%j"))
