Truncate single-case data
This function truncates data points at the beginning and / or end each phase.
truncate_phase( data, dvar, pvar, truncate = list(A = c(0, 0), B = c(0, 0)), na = TRUE ) truncateSC(...)
data |
A single-case data frame. See |
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. |
... |
Further arguments passed to the function. |
A truncated data frame (for each single-case).
