create_cctable: Create a ccTable object

Description

Re-arrange the ccRecord object to table format where each column stands for a variable and each row a record data point. The number of rows will depend on the sampling frequency set in this function. If the original data has a higher recording frequency than the set frequency (freq), the closest data point will be taken. It is suggested the `freq` should not be set lower than the maximum recording frequency in the original dataset.

Usage

create_cctable(rec, conf = NULL, freq = 1)

Arguments

rec

ccRecord

conf

either the path of YAML configuration file or the configuration

freq

a unique sampling frequency (in hours) for all variables. e.g. if freq is set to 1, each row in ccTable will represent a record of one hour.

Value

ccTable
