Description

This function gives an initial guess of the classes of each variable in the merged data.

Usage

var.class(nametable.class, dataset.class)

Arguments

A matrix of the matched variable names. The number of columns is equal to the number of files. Each row represents a variable that is going to be merged. Any elements except NA in nametable.class must be the variable names in dataset.class.

dataset.class

The dataset list. The length of the list is equal to the number of files, and the order of the list is the same as the order of columns in nametable.class.

A vector matching the rows of 'nametable.class'. The value includes NA if any variable are only NA's.

Examples

a = data.frame(aa = 1:5, ab = LETTERS[6:2], ac = as.logical(c(0, 1, 0, NA, 0)))
b = data.frame(b1 = letters[12:14], b2 = 3:1)
dat = list(a, b)
name = matrix(c("ab", "aa", "ac", "b1", "b2", NA), ncol = 2)
var.class(name, dat)
