Without a reproducible example that includes some sample data (fake is fine), the code you used (NOT in HTML format), and some clear idea of what output you expect, it's impossible to figure out how to help you. Here are some suggestions for creating a good reproducible example: http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example
Without knowing what you want, it looks like abscissa is a vector, and so I'm not sure how this defines a grid, but length(unique(diff(vec))) might help. Note that this DOES NOT account for machine precision in any way. Sarah On Mon, Apr 6, 2015 at 7:50 AM, Marc Lamblin <marcgg.lamb...@gmail.com> wrote: > I need to control of a given grid is uniform.
