Either of these two gives you the answer

more specifically, read ?par and in particular, the entry for parameter
'mar' and it's relatives.

You might also need to add the axis label separately from the figure:

opar <- par(mar = c(5,7,4,2) +0.1)
plot(1:10, ann = FALSE) # or plot(1:10, ylab = "")
mtext("label", side = 2, line = 6)
par(opar)

1) opar <- par(mar = c(5,7,4,2) +0.1) creates 7.1 lines on the left of
the plot and saves defaults
2) mtext("label", side = 2, line = 6) displays the axis label on line 6
to push it away from the plot axis. Repeat for other sides...
3) par(opar) resets to the defaults.
