Print an Object

Description

Print the results of the regional seasonal Kendall trend test.

Usage

## S3 method for class 'rsktest'
print(x, digits = 4, ...)

Arguments

x	the object to be printed, must be the output from regionalSeaken.
digits	the number of digits to use when printing numeric values.
...	further arguments for other methods.

Value

The object is returned invisibly.

Note

Three p-values are printed for the analysis. The raw p-value is based only on the computed variance of S. The p-value corrected for serial correlation includes the adjustement described in Hirsh and Slack. The p-value corected for serial and spatial correlation also includes the adjustment based on Dietz and Killeen (1981) described in Sprague and others (2009). An alternative corrected value based on the methods described Douglas and others (2000) is also printed.
