Test for an empty *pas* object

Source: R/utils-pas.R

Convenience function for `nrow(pas) == 0`. This makes for more readable code in functions that need to test for this.

pas_isEmpty(pas = NULL)

Arguments

pas

A *PurpleAir_synoptic* object.

Value

`TRUE` if no data exist in `pas`, `FALSE` otherwise.

Examples

library(AirSensor2)
example_pas_pm25 %>% pas_isEmpty() %>% print()
#> [1] FALSE
example_pas_pm25 %>% pas_filter(latitude > 90) %>% pas_isEmpty() %>% print()
#> [1] TRUE
