| quantile.im {spatstat} | R Documentation |
Compute the sample quantiles of the pixel values of a given pixel image.
## S3 method for class 'im': quantile(x, ...)
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. See quantile.default.
|
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.
A vector of quantiles.
