how do i plot this "hist"?
Typing too fast; last line should be: barplot(t(x.m[, 2:5]), names.arg = x.m[,1], las=2)

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