Check legend icons in online version

[arunge]

With version 23.04.2 on iso-app beta the option to use symbols on the interactive map is online. However, there is an issue with the legend. Online the figures for the legend icons cannot be found. This did not happen locally, I will check what is going on here:

@jan-abel-inwt Something is not working online, maybe an issue with paths to the files where icons (that must be created in advance) are stored. Please let us check this together.

The idea to use system.file() did not help, the points still cannot be found in the online version:

Fixed, see https://github.com/Pandora-IsoMemo/iso-app/issues/148#issuecomment-1540690444

Notes:

• It was important to use the folder dist to store created icons:
  • path <- system.file("dist", package = "MpiIsoApp")
• Possibly because dist is registered in zzz.R

  .onLoad <- function(libname, pkgname) {
  shiny::addResourcePath(
  "IsoMemo",
  system.file("dist", package = "MpiIsoApp")
  )
  }

• and the app was able to find the path: "IsoMemo/.png"

  path <- path %>%
    gsub(pattern = ".*dist", replacement = "IsoMemo")
