Description Usage Arguments Value Author(s) See Also Examples

This function truncates data points at the beginning and / or end each phase.

truncateSC(
  data,
  dvar,
  pvar,
  truncate = list(A = c(0, 0), B = c(0, 0)),
  na = TRUE
)

`data`	A single-case data frame. See `scdf` to learn about this format.
`dvar`	Character string with the name of the dependent variable. Defaults to the attributes in the scdf file.
`pvar`	Character string with the name of the phase variable. Defaults to the attributes in the scdf file.
`truncate`	A list with a vector of two (beginning and end) values for each phase defining the number of data points to be deleted. For lists of single-case data frames, the truncation is adapted to the length of each phase for each single case.
`na`	If FALSE, the truncated measurement times are deletet. If TRUE, NAs are set for the dependent variable.

A truncated data frame (for each single-case).
