missing lines when read csv file into R

Question

I have trouble with reading csv file into R. The file contains more than 10000 lines, but only 4977 lines are read into R. And there is no missing value in the file. My code below:

mydata = read.csv("12260101.csv", quote = "\"", skipNul = TRUE)
write.csv(mydata, "check.csv")

Answer 1

It's hard to say without seeing the CSV file. You might want to compare rows that aren't being imported with the imported ones. I would try using the function read_csv() from the package readr or fread() from data.table .

Answer 2

As other posters pointed out, hard to reproduce without an example. I had a similar issue with read.csv but fread worked without any problems. Might be worth a shot to give it a try.
