error with get_elev_point

[mhweber]

@jhollist , I'm guessing this may be related to changes with PROJ but running elevatr vignette code, as well as my own data, with get_elev_point is consistently returning error. Using:

   library(sp)
   library(elevatr)
   set.seed(65.7)
   examp_df <- data.frame(x = runif(3, min = -73, max = -72.5), 
                   y = runif(3, min = 42 , max = 43))
   prj_dd <- "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs"
   # Create and example data.frame with additional columns
   cats <- data.frame(category = c("H", "M", "L"))
   examp_df2 <- data.frame(examp_df, cats)
   # Create an example SpatialPoints
   examp_sp <- SpatialPoints(examp_df, proj4string = CRS(prj_dd))
   # Create an example SpatialPointsDataFrame
    examp_spdf <- SpatialPointsDataFrame(examp_sp, data = cats)

And then running:

   df_elev_epqs <- get_elev_point(examp_df, prj = prj_dd, src = "epqs")

I get:

   Error in h(simpleError(msg, call)) :  error in evaluating the argument 'CRSobj' in selecting a method for function 'spTransform': NA

Same error with all of these:

 df2_elev_epqs <- get_elev_point(examp_df2, prj = prj_dd, src = "epqs")
 sp_elev_epqs <- get_elev_point(examp_sp, src = "epqs")
 spdf_elev_epqs <- get_elev_point(examp_spdf, src = "epqs")

And with this simple example:

test <- data.frame(x=-71.4474, y=44.0945) %>% 
     st_as_sf(coords=c('x','y'),crs=4326)
elev <- get_elev_raster(test, z=10)
# or elev <- get_elev_point(test, src="aws")

Maybe something really simple I'm completely missing? Here's my sessionInfo():

It must be something idiosyncratic with the library configuration I have above - the following code on a different machine with the sessionInfo() shown below works fine - so perhaps can close and consider issue just an edge case with library configuration I have shown above?

   test <- data.frame(x=-71.4474, y=44.0945) %>% 
        st_as_sf(coords=c('x','y'),crs=4326)

    elev <- get_elev_point(test, src="epqs")

solved - fixed by updating rcpp from Rcpp_1.0.7 to Rcpp_1.0.9 and rgdal from rgdal_1.5-23 to rgdal_1.5-32 - not clear if it was rgdal or rcpp update that was needed.

Thanks for reporting the fix! I need to get elevatr switch fully to sf. On my list for the fall.
