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?
