Basic Infix Binary Operators

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

Installation

You can install infix from CRAN:

install.packages("infix")

Or the development version from GitHub:

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:

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.
