#### DataCache: R Package for Managing Data Caches

[![Build Status](https://api.travis-ci.org/jbryer/DataCache.svg)](https://travis-ci.org/jbryer/DataCache?branch=master)

[![CRAN_Status_Badge](http://www.r-pkg.org/badges/version/DataCache)](http://cran.r-project.org/package=DataCache)

The latest development version can be installed using the `devtools` package:

```

devtools::install_github('jbryer/DataCache')

```

#### Example

This example will load weather data.

```

library('weatherData')

library('DataCache')

loadWeatherData <- function(station_id='ALB') {

	return(list(weather=getDetailedWeather(station_id, Sys.Date())))

}

cacheData(loadWeatherData)

cache.info()

cache.info(stale=c('2mins'=nMinutes(2)))

```

Wait two minutes so the cache becomes stale.

```

Sys.sleep(120)

cacheData(loadWeatherData, nMinutes(2))

```
