  1. I went around the block with google maps for a couple of hours and could not get past this cryptic error message when trying to download a simple example map:

    ggmap::register_google(key = APIkey)
    map <- get_map(location = "texas", zoom = 6, source = "stamen")
    Source : https://maps.googleapis.com/maps/api/staticmap?center=texas&zoom=6&size=640x640&scale=2&maptype=terrain&key=xxx
    Error in aperm.default(map, c(2, 1, 3)) : 
      invalid first argument, must be an array
    In addition: Warning message:
    In get_googlemap(center = location, zoom = zoom, filename = filename) :
      HTTP 400 Bad Request

    Others have had this issue and some have solved it--there are some suggestions on stackoverflow--but not me. I tried a bunch of enabling and management options for static maps API, but nothing worked. Maybe something has changed recently with google or ggmap??

    Anyway, I'm now building my maps from scratch using get_stamenmap(). Might be a better future option for map.FLightR.ggmap().

  2. I'm getting an error when running make.prerun.object in FLightR:


    > all.in


    Error in .C("sp_dists", x, y, xx, yy, n, dists, lonlat, PACKAGE = "sp") :

    "sp_dists" not available for .C() for package "sp"


    Looking at the sp package there is a function called spDists, so maybe the name got updated.


    Any thoughts...

  3. Dear Alec,


    The RFID reader will only work with FAT-16 formatted SD cards. The 64GB card is almost certainly FAT-32, and so the RFID reader won't work with it. I know less about what is compatible with iPads. Obviously your mac is compatible with fat16 which will allow it to read smallish SD cards. It could very well be that the iPad will not read Fat16 and that's all there is to it. You could test this idea by taking one of the 2GB cards and reformatting to FAT32 (use disk utility on your mac). If the IPad comms with the reformatted card, then there's your answer. Of course that card will no longer work with the RFID reader. It might be that the lightening interface device is not FAT16 compatible, but I doubt it. You could test that by plugging it into your mac with the FAT16 card attached.
