I tried to change location using setwd(). I can use ggplot2 package and this package working good. So I think my com can't load csv files from dplyr package. and The picture below is my console picture. Where I should fix?

library(tidyverse)
bison <- read_csv('bison_orangecounty.csv')

class(bison)

str(bison)
head(bison)
tail(bison)
