I issued the following command to obtain the std dev for each month.
psd<-numSummary(Sal, groups=month, statistics=c("sd"))
which resulted in
> psd
sd n NA

[1] "list"
I want plot sd versus column 1 (month of year) of the list psd.
The only way I can figure out how to do this is to manually copy the
table into Excel, reformat, and then export that back out as a new csv.
There has to be a better way?
