leaflet - R addPolygons function -


i trying add polygons map, i'm not sure why code not working. i've used same code before on other .shp files, , works fine. obtained spatial file here: http://library.queensu.ca/geo/health_regions. under ontario->local health integrated networks -> 2006 -> boundary files. 

  lhin<- readogr("lhin_divisions/hr035b08.shp",layer = "hr035b08")   leaflet() %>% addtiles()%>%setview(lng=-81,lat=45,zoom=6)   %>%addpolygons(data=lhin,stroke=true, weight=1, col='red')

i feel missing simple, can't figure out what?

the resulting map should have boundaries shown here:http://library.queensu.ca/madgic/free/health_regions/2005/images/lhin_ont.pdf

this work. can change tile color, used black , white since did not know looking for. shapefile in utm no projection. set projection , converted longlat.

proj4string(lhin) <- crs("+proj=utm +ellps=wgs84 +datum=wgs84") lhin <- sptransform(lhin, crs("+proj=longlat +ellps=wgs84 +datum=wgs84")) leaflet() %>% addprovidertiles("stamen.toner") %>% addpolygons(data=lhin,stroke=true, weight=1, color = ~"red")

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
