[R] quantile() and "factors not allowed"

[Joshua Wiley]

Hi Steve,

The basic problem (as the error suggests) is that data of class
"factor" is not allowed in quantile.default.  So one of the elements
of your list must be a factor.  What are the results of:   str(t)  ?
As a side note, since t() is a function, using t as a variable name
can be a bit confusing.

If your list is relative small, you could post the results of dput(t)
which would allow us to see what your data is actually like and
perhaps identify the exact problem and offer a solution.

Cheers,

Josh
