Contains a number of infix binary operators that may be useful in day to day practices.

## Installation

You can install `infix` from CRAN:

``` r

install.packages("infix")

```

Or the development version from GitHub:

``` r

# install.packages("devtools")

devtools::install_github("ebeneditos/infix")

```

## Usage

You can find a full list of operators running `?infix`, but here there are a few examples:

```r

library(infix)

# tryExcept (%except%)

{foo <- "foo"} %except% {foo <- "foo bar"}

print(foo) # "foo"

{ foo <- "foo"

  stop()

} %except% {

  foo <- "foo bar"

}

print(foo) # "foo bar"

# paste0 (%+%)

"01" %+% "jan" %+% "1970" # returns "01jan1970"

# file.path (%//%)

"home" %//% "dir" # returns "home/dir"

# nomatch (%!in%)

4 %!in% 1:3 # returns TRUE

# nil (%||%)

1 %||% 2 # returns 1

NULL %||% 2 # returns 2

# functions logic (%&%, %|% and %xor%)

is.null.na <- is.null %|% is.na

all(is.null.na(NA), is.null.na(NULL)) # returns TRUE

```

Also, `magrittr` pipe-operators (such as `%>%`) are imported.
