calcColumnDiffs: Calculate differences between dataframe columns by row

In wStockhausen/wtsUtilities: Collection of miscellaneous utility functions developed by William Stockhausen

Calculate differences between dataframe columns by row

Description

Function to calculate differences between dataframe columns by row.

Usage

calcColumnDiffs(
  dfr,
  col,
  cols = NULL,
  adjacent = FALSE,
  dropCols = TRUE,
  dropBase = FALSE
)

Arguments

dfr	dataframe
col	column name for base
cols	vector of column names to compute by-row differences for (or NULL)
adjacent	flag to compute differences between "adjacent" columns (default=FALSE)
dropCols	flag to drop original columns involved in differences (default=TRUE)
dropBase	flag to drop base column involved in differences (default=FALSE)

Details

If cols is NULL, then differences will be computed as if cols was the vector of names of columns to the "right" of col. If adjacent=FALSE, then all differences are relative to col as the base. Otherwise, after the first difference, the base column is sequentially moved through those in cols.

Value

copy of input dataframe, with columns inv with extra columns representing column differences
