I have saved an Excel file as Tab delimited, but when I try to open it I get the following error:
a=read.delim("GBM tab")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") : cannot open file 'GBM tab': No such file or directory
While I have a text file named GBM tab in my working directory.
Even when I press Tab, no matches are found. What is the problem?
One easier option is to use file.choose() and then just direct to the file in the directory
a <- read.delim(file.choose())
In the OP's code, it is possible that a file have .txt or .csv at the end it needs to be specified
a <- read.delim("GBM tab.txt")

Everytime I give the command in file.path, it always gives this error message , no matter what.
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file 'C/Users/Jbhanda/Desktop/NEW_GSE52778_All_Sample_FPKM_Matrix.csv': No such file or directory
I need to link my .csv file in desktop to the file.path command in R
First I note you are missing a colon after C, which (assuming this is a Windows machine) should be C:/.
Secondly you can try escaped backslashes:
C:\\Users\\Jbhanda\\Desktop\\NEW_GSE52778_All_Sample_FPKM_Matrix.csv
I'm using Rstudio and I cannot open several file .txt because of this error message :
Error in file(file, "rt") : cannot open the connection
I enter :
X1= read.table("fileX1.txt", header = FALSE)
I don't understand because some of my colleagues use the same function with the same .txt file and it works for them
Since you aren't specifying the path to the file, R will look for it in the current directory. If that isn't the directory containing the file, you'll get that error.
You can use setwd() (or a menu command in RStudio) to set the current directory. Alternatively, you could use file.choose() to get a dialog to choose the file; it will return the full filename including the path.
I am trying to upload a file of csvs and other documents into R studio. My code looks like the following.
setwd("~/Dropbox/R")
getwd()
[1] "/Users/me/Dropbox/R"
myData <-read.csv("~/Dropbox/Exercise_Files")
The message returned is:
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file '/Users/me/Dropbox/R/Exercise_Files': No such file or
directory
I can't understand why R is telling me no such directory when getwd() shows the directory I am using. Nor do I understand why I am being told that there are no such files--I put them into the directory! They are right there! Please help; I have tried everything.
You have to specify the .csv extension:
myData <-read.csv("~/Dropbox/Exercise_Files.csv")
list.files() worked for me. I discovered that all my text files were being seen in R as filename.txt.txt but were seen as filename.txt in the Windows file manager. I changed the files to filename (without '.txt') in Windows and now they read into R correctly.
I am trying to use RTextTools for none .csv files.
data7 <- read_data('/Users/Ziegler1812/Desktop/Essays/Fall 2016/461/Data-PrelimforR/Data-PrelimforR4/', type = 'folder',index = '1.txt',1)
Error in file(file, "rt") : cannot open the connection In addition:
Warning message: In file(file, "rt") : cannot open file '1.txt': No
such file or directory
'1.txt' does in fact exist in that location, the problem is not the file's existence, it is getting to the location of the file.
The problem was that in RTextTools the index is not to be an index from within the folder, it is to either be the folder itself, or an outside entity that is similar to that within the folder. Further, the explanation shows that folder is for txt files, however 'delim' is for txt files, which is why I couldn't get it to work.
Thanks.
This is my question
if i input this to my R data Mining tool
mydata <- read.csv("filename.txt")
it will shows an error like below
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file 'filename.txt': No such file or directory
what can i do to clear this error
Use read.delim("Path of the file like C://Users//Desktop//filename.txt")
which has more options than read.csv
