mapView error when simple features contain ZM dimensions

[kent37]

For example:

library(sf)
library(mapview)

t = st_as_sfc("LINESTRING ZM (-71.433917 42.593903 4250 1498623425.8, -71.433355 42.594131 4250 1498623426.8)", crs=4326)
mapView(t)
## Error in if (length(nms) != n || any(nms == "")) stop("'options' must be a fully named list, or have no names (NULL)") : 
##  missing value where TRUE/FALSE needed
        
mapView(st_zm(t)) # works

Coincidentally, in response to #98 I pushed a fix for this today c41df1e
Hence, with devtools::install_github("r-spatial/mapview@develop") this should no longer fail.

sorry, just realised that the earlier fix was only for class sf. 7372c3c should fix this for class sfc as well

Cool thank you!

BTW if you need real-world XYZM data let me know; mine is airplane flight tracks.

[tim-salabim]

Yes, at some stage we (whoever that may be) will want to progress towards 3d data representation straight from R. I'll keep this in mind thanks!

@kent37 I'd like to try your data in my hypertidy/rangl repo for plotting with rgl, it's been latent for a while but ready for general use - still a bit buggy no doubt, I hadn't tried any xyz sf data yet

[kent37]

@mdsumner OK give me a few days, I'll get you something.

@mdsumner Attached is a zipped shapefile containing 144 flight tracks of aircraft departing runway 33L at Boston Logan airport on Jan 27, 2017. Data is from an ADS-B recorder so it is kind of rough. Each point includes lat, lon, altitude in feet and time in EST. Unzip and read with
st_read('tracks.shp')
tracks.zip

If you are making interactive 3D visualizations of such things I'm interested :-)
