Description Usage Arguments Details See Also Examples
This function generates a graphical representation of the specified 'sample.lt´ object.
1 2 |
samp |
object of class 'sample.lt´. |
type |
Denotes the type of plot that is shown. * If "locations", the group locations in the region is shown, with the survey area shaded in, and each observation indicated by a red dot. * else, a histogram of number of observations against perpendicular distance from transect is plotted. |
show.sizes |
if TRUE different animal group sizes are shown as dots of different sizes. |
show.exps |
if TRUE different group exposures are shown in different shading. |
dsf |
enlargement factor for group dots. |
whole.population |
if TRUE undetected animal groups will be shown in black, as well as detected animal groups shown in red. TRUE is only possible if type="region". |
show.paths |
if TRUE the transect paths will be added as arrows pointing into the direction of the current transect. |
This function displays the result of a survey sample. It shows a picture of the region, the survey units and indicates the detected animal groups as red dots.
