R help - May 2004 - Graphic size with X11 device

Hello,

I have done a script that make multiple graphics : one graphic per 
columns of my data matrix and one x11 window every 4 graphcis. For 
example, if my matrix has 6 columns, there will appears one x11 window 
with 4 graphics and a second one with the last 2 graphics.
I wanted that all graphics have the same size so when I open x11 I 
specify width and height proportional to the number of lines expected by 
window. But in the second windows it is always different in size of the 
graphics, in size of the points and in size of the text.
What do i miss?

Thanks.

Laetitia.

Are you using par(mfrow)?  If so, that changes the base cex for layouts
with 2 or more rows and columns.

Otherwise, the text size should be the same, but in calculating the window 
size you have to compute the device not plot region, that is included the 
margins (and outer margins) which are of fixed size.

I would use par(mfrow=c(2,2)) on all windows, and accept that there will 
be white space on the last one.
