Dear listers, I'm having a bad R day. I just can't think of the vectorized equivalent of: for (ii in 1:n) aa[ii] = bb[ii,cc[ii]] Any suggestion received with embarrassment and gratitude Simon Gatehouse CSIRO Exploration and Mining, Newbigin Close off Julius Ave North Ryde, NSW Mail: PO Box 136, North Ryde NSW 1670, Australia Phone: 61 (2) 9490 8677 Fax: 61 (2) 9490 8921 Mobile: 61 0407 130 635 E-mail: simon.gatehouse at csiro.a...

I wrote a function to calculate cosine distances between rows of a matrix. It uses two loops and is slow. Any suggestions to speed this up?

All: Are there any functions out there for selecting all the points in a region of a plot. I envision something like the identify() function except one could circle a cloud of points (and perhaps a vector would be returned of the same length as the points plotted indicating logical membership in the circled cloud). Perhaps someone has done something with the locator() function that would
