Adjust axis label margins
vector of axis labels
single integer value indicating which margin to adjust,
using the order by par("mar")
, 1=bottom, 2=left, 3=top,
4=right.
fraction less than 1, indicating the maximum size of margin relative to the figure size. Setting margins too large results in an error otherwise.
numeric or NULL, sent to strwidth
when
calculating the string width of labels in inches.
character string used to add whitespace around the axis label.
additional parameters are ignored.
This function takes a vector of axis labels, and the margin where they
will be used, and adjusts the relevant axis margin to accomodate the
label size, up to a maximum fraction of the figure size as defined by
maxFig
. It currently assumes labels are placed perpendicular to
the axis, e.g. las=2
when using text
.
Note this function does not render labels in the figure.
