this helps, thank you.
But if this code is in a function, and some user supplies a vector, I will
still have to round it in the function, I guess.
It's weird how 0.1 is different from round(0.1, digits=1) , but I don't want
to read that 90 page long floating point paper which was referenced
somewhere :)
Or you could try the much shorter R FAQ 7.31. Turns out it
isn't weird at all, if you are a computer.
You're a computer! :)
But yes.. the FAQ entry was where I found all.equal and the referenced
90-page-paper. But I didn't find out how to do a subset with 'somevector
> 0.4'.
I think I'll have to round the numbers every time now.. or use some
other not-so-pretty workaround like 'somevector > 0.4 - 0.05' for
0.1-binned data.
