R help - Apr 2017 - R crashing with ggplot 2d histogram

Hi! R newbie here. I wrote a script for a correlation plot, a 2d histogram
(heatmap-like) with ggplot. I've run it before with a smaller dataset and
it runs on my laptop and does what I want. Now I've extended my dataset
and R is crashing after the last line which is to generate the plot I
guess. I get the R session aborted / fatal error message.

My new dataset is composed of time series for two variables. For each
variable there are 50 time series with 15.000 values each, so it's in
total 15000*50= 7.5E5 coordinates for this 2d histogram. Do I have a
memory problem here or is it just a script issue? Any suggestion to make
it run? An eli5 answer would be appreciated, my R experience is relatively
low, I just use it here and there for plotting. Thanks!

You will much improve your chance of getting useful help if you read
and follow the posting guide (below). In particular:

1. Versions of R and packages?

2. Show us the (minimal) code that "crashes." Can you create a minimal
artificial data set that does this that we can run?

3. Are there error messages? If so, what are they?

Cheers,
Bert
