Let’s consider that we have a CSV file: Sample and we want to read it:

Output:

The R compiler produces this error because there is no CSV file by the name sample in the current working directory.

In this article, we are going to see how to fix the error in file(file, “rt”) : cannot open the connection. When error that one may face in R is:

Error in file(file, "rt") : 
cannot open the connection

In addition: Warning message:
In file(file, "rt") :
 cannot open file 'sample.csv': 
 No such file or directory
