An R object to check.

Value

A logical value: TRUE if x is a planktonr_dat object, otherwise FALSE.

Examples

# Assuming planktonr_dat constructor exists:
my_data <- planktonr_dat(tibble::tibble(a = 1:3, b = 4:6),
                         type = "Phytoplankton",
                         survey = "NRS")

# Check if it's a planktonr_dat object
is_planktonr_dat(my_data) # Returns TRUE
#> [1] TRUE

# Check a regular tibble
is_planktonr_dat(tibble::tibble(a = 1:3)) # Returns FALSE
#> [1] FALSE

# Check a data.frame
is_planktonr_dat(data.frame(x = 1)) # Returns FALSE
#> [1] FALSE
