First, make sure the file name is correct.

Second, try 


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.
