Dear Experts,

I am trying to plot the Hovmueller Diagram (example below), which is time
vs. longitude in R.

http://www.esrl.noaa.gov/psd/cgi-bin/hovmoller/timeplot.pl?var=air&level=1000&mon1=1&mon2=1&dy1=1&dy2=31&yr1=2010&yr2=2011&datatype=operational&type=mean&fxdlon=no&postscript=no&lon1=&lon2=&lat1=&lat2=&cint=&lowr=&highr=&size=100&Submit=Create+Plot

But I couldn't make it work at the moment. Could anyone please suggest me
which package or function in R can plot such a graph?

The data file on hand is like:

Longtitude   Latitude   Time1.....................TimeN
   124            -29
   126            -29          .......................................
   128            -29
     ..             . .

2520 spatial locations corresponding to an 84 (longitude) by 30 (latitude)
grid with 2 degree x 2 degree spacing.

Thank and Regards

Fred
