A small wrapper on 'regexpr' to extract the matches and captured groups
from the match of a regular expression to a character vector.

## Installation

```{r eval = FALSE}
source("https://install-github.me/MangoTheCat/rematch")
```

## Usage

```{r}
library(rematch)
```

```{r}
dates <- c("2016-04-20", "1977-08-08", "not a date", "2016",
  "76-03-02", "2012-06-30", "2015-01-21 19:58")
isodate <- "([0-9]{4})-([0-1][0-9])-([0-3][0-9])"
re_match(text = dates, pattern = isodate)
```

```{r}
isodaten <- "(?<year>[0-9]{4})-(?<month>[0-1][0-9])-(?<day>[0-3][0-9])"
re_match(text = dates, pattern = isodaten)
```
