[R] how to create normalized pdf plot?

[Jannis]

How about googleing:

"r-project probability density"

The fourth link to some pdf file gives you quite a bunch of examples and the functions relevant for your problem (hist() and density() I would guess). Browsing the documentation for these functions (by hitting ?hist or ?density ) gives you the explanation of the parameters of these functions.

P.S. The r-seek website gives you a convenient way to browse R related websites for certain keywords.
