[R] Request for some help: Error when joining multiple csv files together

[Bhaskar Mitra]

Hello Everyone,

I have a bunch of csv files, all with common headers (d1, d2, d3, d4).
When I am trying to join the csv files together, with the following code
(shown below),
I am getting a warning  when the files are joined. The values under columns
d3 and d4 are not joined properly.

The code and the error are given below. I would really appreciate some help
in this regard.

regards,
bhaskar


#---code--------------------------------

df <- list.files(pattern = "*.csv") %>%
  lapply(read_csv) %>%
  bind_rows

#---code--------------------------------

Header of each file:

d1  d2  d3  d4
3   4    NA   NA
4   5   NA   7
5   6   8   8
6   7   8   NA
