Draw a scatter plot of some animals' location with ggplot2 (like plot 2
Overview in app). To add all animals as background, the full data set of
animals is also needed.
plot_loc(loc_data_subset, loc_data = NULL, point_size = 0.1)
Arguments
| loc_data_subset |
A subset of animals. A data.table subset taken from
full data set of all animals location loc_data. Note the id column is
factor with all animals identity as levels. So this subset still have all
identities information, which is needed to color each animal consistently. |
| loc_data |
The full data set of all animals location in combined
data.table format, usually came from combine(). If background is not
needed, this parameter can be skipped and take the default NULL value. In
this case better use named parameter for point_size if needed, like
plot_loc(loc_data_subset, point_size = 0.2) instead of
plot_loc(loc_data_subset, 0.2) otherwise the second parameter will be
interpreted as loc_data. |
| point_size |
The size of point in plot. Denser plot may need smaller
point size. |
Value
A ggplot object.
