Subtract timepoint T0 and remove from data

Description

This function subtracts the values at timepoint T0 from all other timepoints and removes it from the data.

Usage

subtract_T0(
  input_data,
  grouping = c("Group", "Experiment", "Position"),
  value = "Value",
  timepoint = "Timepoint",
  validity = "Validity"
)

Arguments

`input_data`	A data frame containing columns preferably named as 'Position', 'Value', 'Experiment','Validity', and 'Timepoint'.
`grouping`	A character vector specifying the columns to use for grouping. Defaults to c("Experiment", "Position").
`value`	The column containing the values to be modified. Defaults to "Value".
`timepoint`	The column containing the timepoint information. Defaults to "Timepoint".
`validity`	The column containing validity information. Defaults to "Validity".

Details

This function modifies the input data frame by subtracting the value at T0 timepoint from all other timepoints for each plate (i.e. experiment). It then removes the rows with this timepoint from the data frame.
