=======================

which i have used 

abc=read.table("abc.dat")

to read the table into R.

There are two problems:

1- I want the first column of the data to be
the 'column names', how should i read the data?

2- I want to plot the histogram, using the first column as
'x' values, and the 2nd,3rd,4th and 5th columns as the frequencies.

How do I plot it?


I have tried to add a 'row' of variable names to it,
and then read with 'header=T', then the first column 
become 'col.names' as I was expecting it to be.

However, when I plot it using 'hist', 
R uses the 2nd column as the 'x value', where it should be used as
'frequency'.
(the 50,55,60,65,70... should be on the x-axis)

Thanks!

Casper
