l_layer_texts.RdLoon's displays that are based on Cartesian coordinates (i.e. scatterplot, histogram and graph display) allow for layering visual information including polygons, text and rectangles.
l_layer_texts(widget, x, y, text, color = "gray60", size = 6, angle = 0, label = "texts", parent = "root", index = 0, ...)
| widget | widget path name as a string |
|---|---|
| x | the coordinates of line. Alternatively, a single plotting structure,
function or any R object with a plot method can be provided as x and
y are passed on to |
| y | the y coordinates of the line, optional if x is an appropriate structure. |
| text | vector with text strings |
| color | color of line |
| size | font size |
| angle | text rotation |
| label | label used in the layers inspector |
| parent | group layer |
| index | of the newly added layer in its parent group |
| ... | additional state initialization arguments, see
|
layer object handle, layer id
