[R] cleaning up a vector

[mlarkin at rsmas.miami.edu]

I calculated a large vector.  Unfortunately, I have some measurement error
in my data and some of the values in the vector are erroneous.  I ended up
wih some Infs and NaNs in the vector.  I would like to filter out the Inf
and NaN values and only keep the values in my vector that range from 1 to
20.  Is there a way to filter out Infs and NaNs in R and end up with a
clean vector?
