[R] plotting the coordinates versus dates
Hello! I have a dataset with the dates and positions - Lat and Long columns How do I make a scatter plot? Do I have to cbind to combine the Lat and Long columns? Any suggestions will be much appreciated!

Let's assume that you want to plot the dates at the geographical positions (named lat and lon), and that the dates are character strings. plot(lon,lat,main=Dates of the observations, xlab=Longitude,ylab=Latitude,type=n) text(lon,lat,dates) This assumes that you haven't got too many dates, and a fair bit of latitude (and longitude). It should give you an idea of one type of plot.

If you cast your data into the spatial classes for R provided by the sp-pacakge, you can easily make nice plots. After installing sp from CRAN: library(sp) data(meuse) meuse summary(meuse) coordinates(meuse) = ~x+y ?coordinates spplot(meuse, zinc) The r-sig-geo mailing list is more suitable for this kind of question. cheers, Paul -- Drs.
