read.table line 15 does not contain 23 elements - R

问题

here is the code I used:

d = read.table("Movies.txt", 
           sep="\t", 
           col.names=c( "id", "name", "date", "link", "c1", "c2", "c3","c4", "c5", "c6","c7", "c8", "c9","c10", "c11", "c12","c13", "c14", "c15","c16", "c17", "c18", "c19"), 
           fill=FALSE, 
           strip.white=TRUE)

and here is the text file:

It is clear that Line 15 had 23 elements. It is even clearer when in the text editor that there are tabs where they should be. Why would I be getting this error message ?

回答1:

Disable quoting by adding the parameter quote = "" to read.table().

I believe the issue is with the various single ' and double-quotes " throughout the file.

Look at ?read.table for more information. Per the documentation, you can also look at ?scan for how the behavior of quotes embedded in quotes is handled.
