melt_check: Check that input variables to melt are appropriate.

In reshape2: Flexibly Reshape Data: A Reboot of the Reshape Package

Description

If id.vars or measure.vars are missing, melt_check will do its best to impute them. If you only supply one of id.vars and measure.vars, melt will assume the remainder of the variables in the data set belong to the other. If you supply neither, melt will assume discrete variables are id variables and all other are measured.

Usage

melt_check(data, id.vars, measure.vars, variable.name, value.name)

Arguments

data	data frame
id.vars	vector of identifying variable names or indexes
measure.vars	vector of Measured variable names or indexes
variable.name	name of variable used to store measured variable names
value.name	name of variable used to store values

Value

a list giving id and measure variables names.
