Hi R-users:
Yesterday I ran a R code for 9 hours and it did not show any sign to
stop. Then I interrupted it and found it had completed 82.5%.
This morning I decided to wait for another 11 hours to see what will
happen. Wait a minute, I heard that transforming data.frame to matrix
will make R code faster. Then I made the modification in my R code.
Oooh, the new code finished within 30 minutes!!
Are there any other tips to speed up R program? Or someone could
indicate me some documents or websites on R code optimization?

#for() loop: 1000*1616*3*41, 3 data.frames (dim = c(1616,5), c(1616),
c(1616) respectively)
