Warnings about legacy package dependencies

[dmkaplan2000]

Hi,

I noticed that recent versions of tmap warn on load that there are dependencies on legacy packages sp, rgdal, etc. that are going away. I just wanted to make sure that these issues aren't going to impact core tmap functionality, i.e., that the package is going to stick around even if these dependencies disappear. I typically use tmap with sf and stars, so I wouldn't expect to be truly relying on any of these dependencies.

Thanks,
David

Thx @dmkaplan2000
tmap does not use any of those packages anymore (already since 3.0). However, there are indirect dependencies that apparently still do.

Cool, thanks for letting me know.

For example:

library(tools)
pdb <- available.packages()
o1 <- package_dependencies(packages = c("tmap"), pdb, which = "strong", recursive = FALSE, reverse = FALSE)
"sp" %in% o1
# [1] FALSE
o2 <- package_dependencies(packages = o1$tmap, pdb, which = "strong", recursive = FALSE, reverse = FALSE)
sapply(o2, function(x) "sp" %in% x)
#      methods    tmaptools           sf        stars        units         grid 
#        FALSE        FALSE        FALSE        FALSE        FALSE        FALSE 
# RColorBrewer  viridisLite     classInt    htmltools  htmlwidgets  widgetframe 
#        FALSE        FALSE        FALSE        FALSE        FALSE        FALSE 
#      leaflet     leafsync       leafem        stats        abind        rlang 
#         TRUE        FALSE        FALSE        FALSE        FALSE        FALSE 
#        utils 
#       FALSE 

so it looks like leaflet.

Thanks @rsbivand I saw that you already issued this rstudio/leaflet#833
