zipR version 0.1.0

An R library for zip()

This library does one thing, and one thing only: implementing Python-style* zip() for R.

To install

install.packages("zipR")

* without the functionality of iterators or tuples.

Quick demo

library(zipR)

Dummy data

Some sequences of different lengths, in order to test the different options available in zipr.

a <- c(1,2,3)
b <- c(4,5,6)
c <- c(1,2,3,4,5,6)
d <- c(7,8)
z <- c(9)
filler <- c(NA)

zip two vectors of the same length

zipR::zipr(a,b)

zip two vectors of different lengths, repeating the shorter vector

broadcast = TRUE repeats elements of the shorter vector so that it is the same length as the longer vector

zipr(a, z, broadcast = TRUE)

zipr(a, c, broadcast = TRUE)

zip two vectors of different lengths, using the default fill value

fill = TRUE without a fillvalue specified fills in the shorter vector with NA

zipr(z, a, fill = TRUE)

zip two vectors of different lengths, using a custom fill value

zipr(c,a, fill = TRUE, fillvalue = z)

zipr(c,z, fill = TRUE, fillvalue = d)

The demo for zipR is also available here.
