Examples

## Not run: 
# Show that bci_elevation and bci_matrix contain the same information. They
# justdiffer in the class.
# library(tidyverse)
# library(bciex)
# 
# # Class is different
# class(bci_mat)
# class(bci_elevation)
# 
# # But contents are the same.
# # Tidy mat: each variable in a column; each observation in a row
# mat <- to_xy_value(bci_mat, grid = c(y = 5, x = 5))
# mat <- rename(mat, elev = value)
# # Arrange in the same way
# mat <- mat %>% arrange(x, y, elev)
# elev <- bci_elevation %>% arrange(x, y, elev)
# identical(mat, elev)

## End(Not run)
