Good day to you all,
I have lightning data containing date, time, latitude and longitude. I hope
that distribution of latitude and longitude will give number of lightning
occurrence in a region. I have used factor function to sum up the number of
events on latitude and longitude axis and saved as x and y. But when I tried
to plot the two, I had and error message ( Error in image.default(x, y, z) :
increasing 'x' and 'y' values expected). Every other effort I made failed to
be successful - please I am a new user of R. Part of the data I am using is:

lat            lon
-5.1821 147.4462
-5.1826 147.3733
-5.1680 147.3855
31.4489 -63.2175
28.3199 -62.1831
-18.2495 -44.6471
-11.3654 -42.8249
-2.6652 -73.2344
-13.3543 -56.5338
27.9594 -157.9413
29.4454 -62.0620
-5.1953 116.0678
31.7057 -62.7211
-15.6194 124.6710
-7.1434 -72.2230
-19.1066 -45.6655
I would be extremely grateful should anyone be king enough as to guide me on
how to handle this plot.
Thank you for any help.
