Error in file(file, “rt”) : cannot open the connection [duplicate]

Answer 1

Error in file(file, "rt") :

I just faced the same error and resolved by removing spacing in address using paste0 instead of paste

filepath=paste0(directory,"/",filename[1],sep="")

Answer 2

Set your working directory one level/folder higher. For example, if it is already set as:

setwd("C:/Users/Z/Desktop/Files/RStudio/Coursera/specdata")

go up one level back and set it as:

setwd("C:/Users/Z/Desktop/Files/RStudio/Coursera")

In other words, do not make "specdata" folder as your working directory.

Answer 3

close your R studio and run it again as an administrator. That did the magic for me. Hope it works for you and anyone going through this too.

Answer 4

You need to change directory <- ("./specdata") to directory <- ("./specdata/")

Relative to your current working directory, you are looking for the file 001.csv, which is in your specdata directory.

This question is nearly impossible to answer without any context, since you have not provided us with the structure of your working directory here. Fortunately for you, I have already taken R Programming on Coursera, so I already did this homework question.

Answer 5

Use setwd() to change to appropriate directory. Use only filename to access any file in the working directory. Navigate a folder above by using "../<filename>".

Answer 6

One better check that can be done if you get such error while accessing a file is to use the file.exists("file_path/file_name") function. This function will return TRUE if the file is existing and accessible, else False.
