[R] Graphical Parameters

[amna khan]

Hi Sir

There is a difficulty in creating a comprehensive graph.
Suppose I have a time series from 1967 to 2006. I have used the following R
code for creating a graph.

>plot(Year,Dir,ylab="Annual Maximum Daily Rainfall (mm)",cex.lab=1.3
,type="o",lab=c(20,20,25),mgp=c(2.5,1,0),tck=1)
The graph is attached with this email.
Sir I want the grid lines as dashed lines. Second thing to be asked is that
the grid lines should make squared blocks not rectangles. Moreover the
boundries are not in good format.

Sir I request you to please guide in this regards.

Thank You.
