Convert data in wide format to long format

Description

Long format duplicates certain columns and adds rows for which one new column hold values coming from a set of columns in wide format. Does not allow for parallel reshaping.

Usage

reshape.long(
  d,
  vars = NULL,
  factorColumn = "factor",
  valueColumn = "value",
  factors = as.factor(vars),
  rowNamesAs = NULL
)

Arguments

d	data frame with columns in wide format
vars	columns in wide format by name or index
factorColumn	name of the column to be created for the factor
valueColumn	name of the new column of values that were in wide format
factors	vars can be grouped. For each level of factor a new row is created. Implies that length(vars) is a multiple of length(levels(factor))
rowNamesAs	name of the column that should contain row names

Value

data frame in long format
