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?

I am just beginning to use Sweave with Lyx on a Mac (R2.8.1). I have 12 chunks of Sweave code that work fine, but this piece: <<>>= library(car) cabbages$Year<-recode(cabbages$Year,"'X2001'='2001';'X2002'='2002';'X2003'='2003';'X2004'='2004';'X2005'='2005';'X2006'='2006';'X2007'='2007';'X2008'='2008';'X2009'='2009';'X2010'='2010';...

df=data.frame(country=c("A","A","A","B","B","B"), food=rep(c("Apples","Pears","Bananas"),2), X2000=c(4,5,6,7,6,8), X2001=c(4,5,6,7,6,8), X2002=c(4,5,6,7,6,8), X2003=c(4,5,6,7,6,8)); I have data in the above form trying to get a plot of each fruit over time year conditioned on country and food. I tried, xyplot(X2000+X2001+X2002+X2003~2000:2003|country*food,df) But think I need to transform the data, just n...

I have a file, each column of which is a separate year, and each row of each column is mean precipitation for that month. Looks like this (except it goes back to 1964). month X2000 X2001 X2002 X2003 X2004 X2005 X2006 X2007 X2008 X2009 1 1.600 1.010 4.320 2.110 0.925 3.275 3.460 0.675 1.315 2.920 2 2.960 3.905 3.230 2.380 2.720 1.880 2.430 1.380 2.480 2.380 3 1.240 1.815 1.755 1.785 1.250 3.940 10.025 0.420 2.845 2.460...
