Details

Uses slice_sample to do the sampling, n is converted either to prop or n based on its size. Negative values are treated the same as in slice_sample

Examples

data(exStudy)
nDetections(exStudy)
halfData <- sampleDetector(exStudy, n=0.5)
# there are odd numbers of rows in some detectors, so less than half
nDetections(exStudy)
oneDetPerDetector <- sampleDetector(exStudy, n=1)
nDetections(exStudy)
