Examples

 library(sf)
 pts <- data.frame(ID=paste0("ob",1:15), x=runif(15, 480933, 504250), 
                   y=runif(15, 4479433, 4535122))
   pts <- st_as_sf(pts, coords = c("x", "y"), 
                   crs = 32611, agr = "constant") 
 
 # Create distance matrix  
 dm <- st_distance(pts)
   class(dm) <- setdiff(class(dm), "units")  
     attr(dm, "units") <- NULL
   colnames(dm) <- pts$ID 
   rownames(dm) <- pts$ID
 
 # Coerce to data.frame with TO and FROM ID's and associated distance
 dm.df <- dmatrix.df(dm)
   head(dm.df)
