Thanks for the help, everyone. However, no solution yet...
My vectors names are neatly stored in a character vector of their own. This
happens based on how they were imported. So, say I have vectors a, b and c,
all with numeric-only contents. Then I have another vector, say z, that
looks like this:
z<-c("a","b","c")
Is there really no way to tell boxplot to plot the contents of a, b and c
while only referencing z?! Why is this so difficult?? Again, this is part
of an automated process, so the number of incoming data sets, etc. will
vary, which is why I'm seeking a solution this way.
