Compute results using an arbitrary function on columns in a dataframe, by a set of factor levels

Description

Function to compute results from an arbitrary function (fcn) on colunms in a dataframe, by a set of factor levels

Usage

computeFunctionByFactors(
  df,
  fcn = "sum",
  factors = NULL,
  vars = NULL,
  sortBy = NULL,
  ascending = TRUE,
  debug = FALSE
)

Arguments

df	dataframe (or object that can be cast to a dataframe) with variables and factors
fcn	function name AS CHARACTER STRING to apply to each var in vars by each unique factor level combination
factors	vector of names of columns in df to serve as factors in the function applications
vars	vector of names of column in df that the function should be applied to
sortBy	vector of factor column names to sort results by
ascending	flag (T/F) to sort in ascending/descending order
debug	flag (T/F) to print debugging info

Value

  dataframe of results with columns corresponding to factors and vars
