match_data_frame

MatchDataFrame

Description

Given two data frames with the same data, but with rows and columns in potentially different orders, produce a pair of permutations such that data2[row.permutation, column.permutation] matches data1.

Usage

MatchDataFrame(data.to.match, data.to.permute)

Arguments

`data.to.match`	The data frame to be matched.
`data.to.permute`	The data frame to be permuted.

Value

Returns a list with two elements.

`column.permutation`	A vector of indices such that the columns of `data2[, column.permutation]` match the columns of `data1`. The matching is based on column names.
`row.permutation`	A vector of indices such that the rows of `data2[row.permutation, column.permutation]` match the rows of `data1`. The matching is done by converting rows to strings, and matching the strings.

Examples

x1 <- data.frame(larry = rnorm(10), moe = 1:10, curly = rpois(10, 2))
 x2 <- x1[c(1:5, 10:6), c(3, 1, 2)]

 m <- MatchDataFrame(x1, x2)
 x2[m$row.permutation, m$column.permutation] == x1  ## all TRUE
