Can't reproduce README results

[lorenzwalthert]

When I try to use the tiles() function from your package as indicated in the README, I get an error. This is also the #Not run example in ?tiles.

reprex::reprex_info()
#> Created by the reprex package v0.1.1.9000 on 2017-12-12

library(magick)
#> Linking to ImageMagick 6.9.9.25
#> Enabled features: cairo, fontconfig, freetype, fftw, lcms, pango, rsvg, webp
#> Disabled features: ghostscript, x11
library(collage)

files <- list.files(system.file("base", package = "collage"), pattern = "jpg$", full.names = TRUE)
samples <- tiles(files, size = 25)
#> Error in .x[[...]]: subscript out of bounds

Are there additional system requirements I don't meet? Was wondering about Disabled features: ghostscript, x11 but could not find anything online quickly.

@lorenzwalthert, were you ever able to resolve this issue?

I just tried again by installing from GitHub and I get the same error.
