Test "highlight_combinaison.R" fails on Debian

[mr-c]

Hello,

Thank you for your open source software. While packaging it for Debian I ran into the following failed test. I'm not an R developer, so let me know if I'm missing something basic.

BEGIN TEST highlight_combinaison.R

Error in visNetwork(nodes, edges) %>% visOptions(highlightNearest = list(enabled = T,  : 
  could not find function "%>%"

This is from the CRAN 2.0.5 release of visNetwork

Looks like the description now requires magrittr--which is the package where the %>% comes from. So that error should be fixed now? Otherwise, just calling library(magrittr) should get the example to run.
