Hi again all, I can read all of the data is in CSV format with a header row and with 1,200,240 rows. I can do all the plots and ggplot2 has no problems. Seems to be a problem with the MASS package??? It seems that the contour plots are the problem with the memory error. Error: cannot allocate vector of size 228.9 Mb I can run smaller data sets and do the contour plots w/o problems. The data can not really be summarized as I need to plot the actual values to get the insight into the large data sets.
Why can't you divide the plot into, say, four regions with a quarter of the data and draw contours for each region, and then overlay the printed output? -thomas
