A length-1 logical with "status", "message", and "bbox" attributes. On success, the "bbox" attribute contains the validated bounding box in EPSG:4326.

Examples

is_valid_bbox(c(-120, 34, -119, 35))  # TRUE
#> [1] TRUE
#> attr(,"status")
#> [1] "valid"
#> attr(,"bbox")
#> [1] -120   34 -119   35
is_valid_bbox(c(-119, 34, -120, 35))  # FALSE
#> [1] FALSE
#> attr(,"message")
#> [1] "You supplied bbox = c(xmin = -119, ymin = 34, xmax = -120, ymax = 35). `xmin` must be less than `xmax`. "
#> attr(,"status")
#> [1] "invalid"
#> attr(,"bbox")
#> [1] -119   34 -120   35
