Warning message: In file(file, "rt")

Question

I am trying to import CSV files to graph for a project. I'm using R 2.15.2 on a Mac OS X.

• The first way tried

  The script I'm trying to run to import the CSV file is this:

  group4 <- read.csv("XXXX.csv", header=T)
  

  But I keep getting this error message:

  Error in read.table(file = file, header = header, sep = sep, quote = quote,  : 
    object 'XXXXXX.csv' not found 
  

• The second way tried

  I tried moving my working directory but got another error saying I can't move my working directory. So I went into Preferences tab and changed the working directory to the file that has my CSV files. But I still get the same error(as the first way).

• The third way tried

  Then I tried this script:

  group4 <- read.table(file.choose(), sep="\t", header=T)
  

  And I get this error:

  Warning message: 
  In read.table(file.choose(), sep = "\t", header = T) :
    incomplete final line found by readTableHeader on '/Users/xxxxxx/Documents/Programming/R/xxxxxx/xxxxxx.csv' 
  

I've searched on the R site and all over the Internet, and nothing has got me to the point where I can import this simple CSV file into the R console.

Answer 1

1. The file is not in your working directory, change it, or use an absolute path.
2. Than you are pointing to a non-existing directory, or you do not have write privileges there.
3. The last line of your file is malformed.
