list.icon

[tjebo]

the ggimage::list.icon function uses a helper function which looks for png files. This is really not useful, as the icons are svg files. Below a suggestion for a modification - happy to submit pull request if interested.

list_images <- function (url, filetype = "svg") 
{
  x <- readLines(url)
  y <- x[grep(paste0("title=\"[a-zA-Z0-9\\-]+\\.", filetype), x)]
  sub(paste0(".*title=\"([a-zA-Z0-9\\-]+)\\.",filetype, ".*"), "\\1", y)
}

list_icon <- function(){
  list_images("https://github.com/ionic-team/ionicons/tree/master/src/svg")
}

head(list_icon(), 10)
