mmv: Maximal mean values.

Description

Calculate maximal mean values for specified time periods.

Usage

mmv(data, column, pds, delta = NULL, verbose = TRUE, .uniform = FALSE,
  .correct = FALSE)

Arguments

data

a formatted dataset produced by read*().

column

column in data giving the values of interest. Needn't be quoted.

pds

window size(s) for which to generate best averages, given in seconds.

delta

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

verbose

should messages be printed to the console?

.uniform

are the rows of the data already uniform?

.correct

should corrected power values be generated? Mainly for internal use.

Value

• a matrix object with two rows: 1) best mean value(s) and 2) the time at which that value was recorded

Examples

data(cycling_data)
# Generate best powers for 5, 10 and 20 minutes.
t_sec <- c(5, 10, 20) * 60
x <- mmv(cycling_data, power.W, t_sec)
# Show when those values were recorded in minutes
x[2, ] / 60
