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 plural of anecdote is not data.

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, 

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.
