Usage
# S3 method for im
quantile(x, …)Arguments
- x
A pixel image. An object of class
"im".- …
Optional arguments passed to
quantile.default. They determine the probabilities for which quantiles should be computed. Seequantile.default.
Details
This simple function applies the generic quantile operation
to the pixel values of the image x.
This function is a convenient way to inspect an image and to obtain summary statistics. See the examples.
Value
A vector of quantiles.
