Hi,
I used the density function in the R package, and got the following
results. I just wonder how to explain them.
What is Min, 1st Qu, Median, and so on? I could not find an explanation
from help(density). The plot doesn't seem to match
the x and y value either.
Thanks in advance for any help that you can give me!
Hui

The values above are the summaries (see ?summary) for those x and y values calculated by print.density() ...
