Hello,

I'm attempting to write a code that automatically imports data from
different files (with different lengths-just one variable) and makes tidy
box plots for comparison. I can successfully import the data and create a
list of the vectors I want to compare. But I cannot, for the life of me,
figure out how to generate box plots using the "list" option. Suppose these
are my data:

a<-c(1,1,1,1,2,3,2,1,2,3)
b<-c(2,2,2,3,4,4,4,3,3)
c<-c(4,3,3,2,3,4,5,3,3,3,4,4,5,6,3,2)

And this is my list of the vectors I'm interested in:

 z<-list(c("a","b","c"))

Well, this successfully generates the kind of boxplot I want:

boxplot(a,b,c)

But this does not:

boxplot(z)

Because I'm trying to write an automatic plot-generator as the amount of
data I'm working with will typically vary, I need to write this to handle
any number of data vectors.

I've tried every imaginable means of tweaking the name of "z", with zero
success. And I've scoured the help pages for about 45 minutes (just to
preempt any "read the help" responses). Please help!

Thanks,
Ryan
