What is the equivalent of df <- df[complete.cases(df), ] for sf objects?
I know sf objects behave mostly like dataframes with a "sticky" geometry column, but running the above code returns the following error:
df <- df[complete.cases(df), ]
Error in complete.cases(df) : invalid 'type' (list) of argument
This is likely due to sf objects storing their geometry variables as lists. Your input is appreciated!
You can use sf::st_is_empty() to check for empty geometries
library(sf)
pt1 <- sf::st_sfc(sf::st_point())
pt2 <- sf::st_sfc(sf::st_point(c(0,0)))
sf <- sf::st_sf(geometry = c(pt1, pt2))
sf[!sf::st_is_empty(sf), ]
