Problem with Cleaning US Census Data with R


I’m doing the project Cleaning US Census Data with R and I’m stuck at the beginning. I’ve redone it at least 3 times, and I’ve watched the video, but I can’t see what the problem is. Can anyone please tell me what I’m doing wrong here.

library(readr) library(dplyr) library(tidyr)
files <- list.files(pattern = “states_*.csv”) df_list <- lapply(files,read_csv) us_census <- bind_rows(df_list)

Thank you in advance for any help you can offer!
