Here is a simple 3-step solution:
1. type ?barplot
2. find the section labelled 'Arguments'
3. carefully read what each argument means/does
Voila, problem(s) solved.
(It was good to include some data, but not so good
to say that title(...) is giving "an error". No need
to be secretive about the error; just say what it was.)

Hello
(this might be a very simple question)
My data is as follows (table name is student)
Year StudentsPassed
1 2000 300
2 2001 360
3 2002 450
4 2003 450
5 2004 270
6 2005 280
7 2006 400
8 2007 270
I want to plot a barplot so for this
If I use barplot(students) it says "Error in barplot.default(students) :
'height' must be a vector or a matrix"
so I used the following command
barplot(StudentsPassed)
But this doesnt give me the names for Xaxis, how can I get the names for
Xaxis, also how can I get labels for X and Y axis, and tittle, I tried
title(main = "Year Vs Number of Publications")
to get the title but its giving me an error
Thanks in advance
Sunita
I want to
