R.record {RecordTest}

Record Values

Description

Returns the record values of the values in a vector. A record value is the magnitude of a record observation.

If the argument X is a matrix, then each column is treated as a different vector.

Usage

R.record(X, record = c("upper", "lower"), weak = FALSE)

Arguments

X

A numeric vector, matrix (or data frame).

record

A character string indicating the type of record to be calculated, "upper" or "lower".

weak

Logical. If TRUE, weak records are also counted. Default to FALSE.

Details

The sequence of record values \{R_1,\ldots,R_I\} can be expressed in terms of the record times L.record by

R_i = X_{L_i}.

Record values can be calculated for both upper and lower records.

Value

If X is a vector, the function returns a list containing the vector of record values. If X is a matrix, the function returns a list where each element is a vector indicating the record values of the corresponding X column.
