Problem with read.table in my Mac. "No such file or directory"

Thanks.  I switched from years using PCs about a year ago when MS would no longer support Windows 7.  I have missed seeing extensions on files (probably .txt for this one).  It?s good to learn that I can change that.

Try

list.files()

to see the names of the files in the current directory, and make certain you are where you think you are, the file is there, has the name you think it has etc.  You may need to add the extension, presumably something like ?.csv? to your read.table call.

A possible point of confusion is that  you may have your Mac set to not display file extensions, and life is generally easier in my opinion if those extensions are turned on.   Plenty of advice on the internet as to how to turn this on for all files.

I?m still having trouble with read.table, as follows (and there IS a plain text document called moabsitechem in this directory:

getwd()

read.table("moabsitechem")

Error in file(file, "rt") : cannot open the connection
In addition: Warning message:

How can I fix this problem?
