shift: Shift values in a single-case data file

Description

This function has been superseded by the much more versatile transform.scdf function. Shifting the values might be helpful in cases where the measurement time is given as a time variable (see example below).

Usage

shift(data, value, var)

Value

A scdf with shifted data

Arguments

data

A single-case data frame. See scdf() to learn about this format.

value

Number by which to shift the values

var

Character string with the name of the target variable. Defaults to the measurement time variable.

Other data manipulation functions: add_l2(), as.data.frame.scdf(), as_scdf(), fill_missing(), moving_median(), outlier(), ranks(), rescale(), scdf(), select_cases(), set_vars(), smooth_cases(), standardize(), truncate_phase()

Examples

### Shift the measurement time for a better estimation of the intercept
ex <- shift(example_A24, value = -1996)
plm(ex)

# Please use transform instead:
example_A24 |>
  transform(year = year - 1996) |>
  plm()
