These functions are intended to replace some commonly used base R graphics functions in panel functions.

The proportion of the arrow edges compared to
the whole line. This is different from arrows |

other arguments, including ones to control graphical parameters like
color, line type, etc. For devices that support alpha-transparency,
a numeric argument alpha between 0 and 1 can be supplied. Be
careful with this, since for devices that do not support
alpha-transparency, nothing will be drawn at all if this is set to
anything other than 0.

These functions are meant to be grid replacements of the corresponding
base R graphics functions, to allow existing Trellis code to be used
with minimal modification. The functions panel.* are
essentally identical to the l* versions, are recommended for
use in new code (as opposed to ported code) as they have more readable
names.
See the documentation of the base functions for usage. Not all
arguments are always supported. All these correspond to the default
methods only. For ltext, only values 0, .5 and 1 for adj
have any effect.
There's a new type="H" option wherever appropriate, which is
similar to type="h", but with horizontal lines.
