Usage

index.trend(ts, dates, output = c("coef", "sig"), sig.level = 0.95)

Arguments

ts	A vector containing the data
dates	A character (or POSIXct) vector following the format “YYYY-MM-DD” (i.e., format = "%Y-%m-%d" as in strptime). This is directly passed by the VALUE objects (either stations or predictions) through the element object$Dates$start.
output	Desired output. The options are "coef" for the slope coefficient (default) or "sig", which is a binary value indicating whether the slope coefficient is significant (1) or not (0) at the given sig.level.
sig.level	Significance level. Default to 0.95.

Value

A numeric value with either the slope coefficient (for output = "coef") or whether it is significant (1) or not (0) (output = "sig") at the specified sig.level
