# llines

##### Lattice Replacements of base graphics functions

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

- Keywords
- dplot

##### Usage

```
larrows(x0, y0, x1, y1, proportion, ...)
llines(x, y, ...)
lplot.xy(xy, ...)
lpoints(x, ...)
lsegments(x0, y0, x1, y1, ...)
lsegments(x1, y1, x2, y2, ...)
ltext(x, ...)
panel.arrows(...)
panel.lines(...)
panel.points(...)
panel.segments(...)
panel.text(...)
```

##### Arguments

- x, y, x0, y0, x1, y1, x2, y2, xy
- locations. x2, y2 present for S compatibility
- proportion
- 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 dev

##### Details

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.

##### Note

There's a new `type="H"`

option wherever appropriate, which is
similar to `type="h"`

, but with horizontal lines.
