Those sound like basic questions. You should start by reading the Intro to R that can be found here http://cran.r-project.org/doc/manuals/R-intro.html or at www.r-project.org
For your specific questions, searching for "histogram" or "bar chart" at http://www.rseek.org would be very helpful. If you have problems beyond that, putting together a specific example as requested by the posting guide will generally get you much better advice than vague queries.
