R help - Mar 2005 - plot question

I have the following simple situation:

tt <- data.frame(c(0.5, 1, 0.5))
names(tt) <- "a"
plot(tt$a, type = 'o')

gives the following plot ('I' and '.' represent the axis):

I
I
I     X
I
I
I X       X
I...........
   1   2   3

what do I have to change to get the following:


I
I
I          X
I
I
I      X       X
I.....................
        1   2   3

i.e. the plot-region should be widened at the left and right side

thanks for a hint

Use 'xlim' to specify the range of the x axis:

plot(c(0.5, 1, 0.5), type = 'o', xlim = c(0, 4))

See ?par for more information.

tt <- data.frame(c(0.5, 1, 0.5))
names(tt) <- "a"
plot(tt$a, type = 'o',xlim=c(0,4))

Correction, that should have been ?plot.default for more information,
though ?par has other relevant information on plot parameters as well.

What about:

plot(tt$a, type = 'o',xlim=c(0,4))
