R help - Mar 2012 - Statistical Histograms in R

Hi, 

I'm wondering if anybody could possibly help me? 
I have a table with 5 tab-delimited columns. Each column has 'e-value'
scores for 5 different proteins. 

I'd like to plot a distribution curve using hist() for the 5 different
proteins and show the 5 distribution curves on the same graph in different
colours. 
In the case, E-values will be the X-axis and frequency will be the Y-axis. 

Is this at all possible? 

Thanks.

Have a look at http://had.co.nz/ggplot2/stat_density.html You'll find some
exampled and the code to generate them.

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

The combination of some data and an aching desire for an answer does not ensure
that a reasonable answer can be extracted from a given body of data.

Hi SMcG,
Have a look at the last example for the barp function (plotrix). This
may be what you want.
