naturalsort package

===================

The package provides functions related to human natural ordering.

Installation

------------

```r

install.packages("naturalsort")

```

For `devtools` users, run:

```r

install_github("kos59125/naturalsort", subdir="naturalsort")

```

Usage

-----

```r

library(naturalsort)

## Simple example.

text <- c("a1.png", "a2.png", "a10.png")

print(naturalsort(text))

print(sort(text))  # general sort

## Reordering factors in natural order.

## After read.table with stringsAsFactors=TRUE, levels of column of factor is sorted in character order.

## If you prefer natural ordered factor, call read.table with stringsAsFactors=FALSE and creates factor column manually.

data <- read.table(file, header=TRUE, stringsAsFactors=FALSE)

data$SomeFactor <- factor(data$SomeFactor, levels=naturalsort(unique(data$SomeFactor)))

```
