I have an R newbie question about storing data. I have 3 different files, each of which contains one column. Now I would like to read them into a structure x so that x[1] is the column of the first file, x[2] is the column of the second file, etc. So x would be a two-dim vector. I tried this, but it wants x[f] to be a single number ra...
I'm developing an iPad application and I'm not sure what's the best way to store application data. So far I've been using a .plist that stores hundreds of strings for a puzzle game and that works great, but if my app is to be any good, it's going to have to store tens of thousands of strings (representing pre-made puzzles). I've read t...

I'm monitoring the change in certain values day over day. The changes vary, and can be of any value size, typically 1-100 difference, but maybe there is an outlier at 500 or even 900. I want to be able to put these values on a set scale so I can plot them. Is there a formula I can use to limit the high end of the scale, so no matter...
