lasso and marquee allow the user to subset telemetry data into two groups (interior and exterior), based on a hand-drawn polygon lasso or rectangular marquee. cleave allows the user to split the data into two halves at a particular time selected via slider.
lasso and marquee return a named list telemetry objects, twice the length of the input object, where the first half are the interior subsets and the second half are the exterior subsets. cleave stores a similar list of telemetry objects to name on button press.

# This example is interactive
if(interactive())
{
# Load package and data
library(ctmm)
data(wolf)
# Extract wolf Luna
Luna <- wolf$Luna
# Select resident data
Luna.sub <- lasso(Luna)
# You can now work with the resident and dispersive data separately
names(Luna.sub)
