How do I post text-string dates along the x-axis instead of the excel_date position values?
I would like to plot a time-series of chemical values changing with time The first column is the internal date from excel. This should be the x-axis position of a graph of the plotted data. The second column is a text-string of date. This should be what is posted (instead of the excel_date). The third column is the chemical data and this should be the position of a point on the y-axis. A line needs to connect the points but should break at the NA. excel_date real_date chemical 36234 15-Mar-99 1.6 36302 22-May-99 0.195 36395 23-Aug-99 4.9 36475 11-Nov-99 NA 36593 8-Mar-00 3.58 Rex ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
