cycleRtools (version 1.0.4)

uniform: Create a uniform data.frame.

Description

Returns a data frame with rows that are uniformly incremented along the first column. Useful for rolling operations, whereby a rolling time window is of interest.

Usage

uniform(data, delta = NULL, verbose = TRUE, .return_delta = FALSE)

Arguments

data

a data.frame or matrix object to make uniform. This is done on the basis of the first column.

delta

the incremement by which to make the data uniform. If NULL (default) the most appropriate value is estimated.

verbose

should messages be printed to the console?

.return_delta

if TRUE the delta value is assigned to the calling environment. Intended for internal use.

Value

• A uniform data frame. An index column is appended so that original data values can be extracted - e.g. after a rolling operation.

Examples

t_sec <- c(1:10, 20:40, 50)            # Discontinuous timer values.
pwr   <- runif(length(t_sec), 0, 400)  # Some power values.
x     <- data.frame(t_sec, pwr)
uniform(x)
