This library does one thing, and one thing only: implementing Python-style* zip() for R.
install.packages("zipR")
* without the functionality of iterators or tuples.
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) #> x y #> 1 1 4 #> 2 2 5 #> 3 3 6zip 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) #> x y #> 1 1 9 #> 2 2 9 #> 3 3 9 zipr(a, c, broadcast = TRUE) #> x y #> 1 1 1 #> 2 2 2 #> 3 3 3 #> 4 1 4 #> 5 2 5 #> 6 3 6zip 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) #> x y #> 1 9 1 #> 2 NA 2 #> 3 NA 3zip two vectors of different lengths, using a custom fill value
zipr(c,a, fill = TRUE, fillvalue = z) #> x y #> 1 1 1 #> 2 2 2 #> 3 3 3 #> 4 4 9 #> 5 5 9 #> 6 6 9 zipr(c,z, fill = TRUE, fillvalue = d) #> x y #> 1 1 9 #> 2 2 7 #> 3 3 8 #> 4 4 7 #> 5 5 8 #> 6 6 7
The demo for zipR is also available here.
