dir	deployment directory
sub	subsampling interval, in s

Examples

# get example deployments included with the package
deploys <- system.file("extdata", "deployments", package = "discr")
# copy them to a writable, temporary directory
temp <- tempdir()
file.copy(deploys, temp, recursive=TRUE)
dd <- paste0(temp, "/deployments/")
deploy1 <- paste0(dd, "1")

# run the action
disc_conf(deploy.dir=dd)
## Not run: disc_camera_compass_angle(dir=deploy1, sub=10, verbose=TRUE)
# the angle is also stored in a file "angle_camera_compass.txt"
list.files(deploy1)
