theme_zoom_X | R Documentation |
A series of convenience functions for the zooming in on the middle or apex regions to various degrees.
In these convenience functions, a single value of x
is expected, which defines the values of the apex
limits other than the point of reference, for example, theme_zoom_T
will fix the T
limit
at 1
, and will adjust the balancing limits according to the argument x. Equivalent are also possible for
the L
and R
apexes, via the theme_zoom_L
and theme_zoom_R
functions respectively.
Finally, the theme_zoom_center
function will adjust all three apex limits, serving, as the name suggests,
to act as a centred zoom. The examples below are fairly self explanatory.
theme_zoom_T(x = 1, ...)
theme_zoom_L(x = 1, ...)
theme_zoom_R(x = 1, ...)
theme_zoom_center(x = 1, ...)
