How to open CSV file in R when R says no such file or directory

Question

I have an excel file that I want to open in R  I tried both of these commands after saving the excel file as a csv file or a text file   read table   or read csv    I think part of the problem is where the file is located  I have it saved on the desk top  What am I missing here   Here is the R output  In file file   rt       cannot open file  Rtrial csv   No such file or directory  gt  help search  read csv    gt  read csv  Rtrial csv   Error in file file   rt     cannot open the connection In addition  Warning message  In file file   rt       cannot open file  Rtrial csv   No such file or directory  gt  read table  tab

Kindly check whether the file name has an extension for example:
```
abc.csv
```
if so remove the .csv extension.
set wd to the folder containing the file (~)
data<-read.csv("abc.csv")

Your data has been read the data object

Here is one way to do it  It uses the ability of R to construct file paths based on the platform and hence will work on both Mac OS and Windows  Moreover  you don t need to convert your xls file to csv  as there are many R packages that will help you read xls directly  e g  gdata package      get user s home directory home   setwd Sys getenv  HOME        construct path to file fpath   file path home   Desktop    RTrial xls       load gdata library to read xls files library gdata      read xls file Rtrial   read xls fpath     Let me know if this works

Another way of reading Excel including the new format xlsx could be the package speedR  https   r-forge r-project org projects speedr    It is an interactive and visual data importer  Besides importing you can filter subset  the existing objects from the R workspace

Sound like you just have an issue with the path  Include the full path  if you use backslashes they need to be escaped   C   folder  folder  Desktop  file csv  or  C  folder folder Desktop file csv    myfile   read csv  C  folder folder Desktop file csv      or read table     It may also be wise to avoid spaces and symbols in your file names  though I m fairly certain spaces are OK

I have experienced that this error occurs when you either move the excel file to the destination other than where your r file is located or when you move your r file to the destination other than where your excel file is located    Good Practice     Keep your  r and  csv files in the same directory  open your  r file from getting into its directory instead of opening the r file from  rstuio s open file option    You also have import Dataset option at Environment Block  just click there and get your required packages installed  amp  from next time use this option to read datasets  You will not get this error again  I also appreciate the above provided answers

MAC OS It happened to me as well  I simply chose from the R toolbar MISC and then chose Change Working Directory  I was able to choose the directory that the  csv file was saved in   When I went back to the command line and typed getwd   the full directory was updated and correct and the read csv function finally worked
