SetIndex: SetIndex, ResetIndex

In stakahama/Rfunctools: A Package for Misc. Functional Programming Tools

Description

Set index like python's DataFrame.set_index(,inplace=False) but works with data frames and character matrices

Usage

SetIndex(x, ...)

## Default S3 method:
SetIndex(x, index = colnames(x)[1])

## S3 method for class 'tbl_df'
SetIndex(x, ...)

ResetIndex(x, ...)

## S3 method for class 'data.frame'
ResetIndex(x, index = "index")

## S3 method for class 'matrix'
ResetIndex(x, ...)

Arguments

x	[data.frame or character matrix] table
index	[character] index number or name

Value

[data.frame or matrix]

Methods (by class)

• default: Sets row name to value of index and removes index from matix/data frame.

• tbl_df: Converts tibble object (which does not accept row names) to data frame before applying SetIndex.default.

• data.frame: Reset index (like dplyr::add_rownames or pandas DataFrame.reset_index(,inplace=False)). Returns data frame with index in first position.

• matrix: Call as.data.frame on matrix and then apply ResetIndex.data.frame.
