I have been trying to import a csv file to r. but I get the same message everytime. the message is

Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file 'Users:/sezginozcan/Downloads/beer.data.csv': No such file or directory

I use mac.
I tried this command also
a<-read.table("clipboard",sep=?\t?,row.names=1,header=T)
Error: unexpected input in "a<-read.table("clipboard",sep=?"

I will appreciate if you help me before I get crazy.
thank you

There's not usually a colon in Mac file paths. I would have expected
"/Users/sezginozcan/Downloads.beer.data.csv" instead. Did you check
that?

More generally, type dir(PATHWHEREYOUTHINKFILEIS) and see if it really
is there.

Something is wrong with those quotes around \t... 

Also, last I needed this, using file="clipboard" to read from the clipboard didn't work on Mac, but file=pipe("pbpaste") did.

First, make sure the file name is correct.

Second, try 

list.files("Users:/sezginozcan/Downloads/")

to see if the file is listed and you are looking in the correct folder.

Third, you may be able to locate and open the file using

A <- read.table(file.choose(), sep="\t", row.names=1, header=T)

I believe that "clipboard" works only on Windows computers.

I think you must have given the path to the file wrong.

Assuming you are using R.app, try

  infile <- file.choose()

And then give infile to the read.csv() function.

Then print the value of infile to find out what the path really is.

Probably, you wanted
  '/Users/sezginozcan/Downloads/beer.data.csv'
