You are assuming that 0.1 is exactly represented. Since it is not, either 0.1
or 1-0.9 will be less than 0.1.
As to what you should do about it... that depends on what you are trying to
accomplish. Whatever it is, you need to use some other approach. Often the
alternative involves using integer
Hi Michael,
In floating point calculation, 1.0-.9 is not exactly 0.1. This is easily seen
by subtracting.

[1] -2.775558e-17
> (1.0-.9)==0.1
[1] FALSE
David is right, you can't "correct" this. You can only compensate by taking
care that you never, ever test whether 2 FP numbers

Shari,
Josh partly answered your question, but his example did not include
rotation because he took out just one factor.
Try:

mt.pc <- principal(mtcars,3,scores=TRUE) #this gives you the
varimax rotated first 3 principal components
#pc.scores <- mt.pc$scores #here are

What is the best way to learn about classes, methods, extending

I know a bit about classes, but would like to learn much more.
Thanks in advance for any advice!

Hi Erin,
One good option would be the official manual:
