[R] Temporal Analysis of variable x; How to select the outlier threshold in R?

For a financial data set with large variance, I'm trying to find the 
outlier threshold of one variable "x" over a two year period. I 
qqplot(x2001, x2002) and found a normal distribution. The latter part of 
the normal distribution did not look linear though. Is there a suitable 
method in R to find the outlier threshold of this variable from 2001 and 
2002  in R?
