I have imported a dataset from a CSV file to a data frame that has lots of null values, but I can't count the number of null values
install.packages("tidyverse")
library(tidyverse)
sample <- read.csv("sample.csv")
colSums(is.na(sample))
ride_id rideable_type started_at ended_at start_station_name start_station_id
0 0 0 0 0 0
end_station_name end_station_id start_lat start_lng end_lat end_lng
0 0 0 0 0 0
