R help - Oct 2007 - Specify plot size

Hello,

I have another (possibly easy) question:

How to specify the size of a plot? When I draw a plot, I can freely change
the size of the window, which is nice for single plots to find the best
height/width ratio, but as I need a lot of plots in my work, I want to look
them all the same, so I need to specify the size in advance.

Thanks for help,
 Christoph

Have you tried using pdf(), postscript(), or jpeg()? All of these have
arguments to specify the height and width of the device.

see

?device

for different devices and their sizes.

Hello
I need to print table width "colum sum" like
X    V1    V2    TOT
A    2    3            5
B    1    6            7
C    4    6           10

how i can do it by table function?

Thanks

Alessandra

Presuming that your object above is a data frame, you can add a new
column using cbind():
> tab
  X V1 V2
1 A  2  3
2 B  1  6
3 C  4  6

> cbind(tab, TOT = tab$V1 + tab$V2)
  X V1 V2 TOT
1 A  2  3   5
2 B  1  6   7
3 C  4  6  10

See ?cbind.

For actual R tables, you can use ?addmargins

HTH,

Marc Schwartz

If it really is of class "table" (or is an array) or you convert it to
such
you can use addmargins.  You may need to read ?addmargins
carefully.
