I must admit I don't know all its history but the original data was taken from
an OOo spreadsheet that I edited (good bit of copying and pasting and the month
variable added by hand in OOo Calc) and, then,saved as a csv file. It was not
originally an English language file as far as I can determine. It may have
been created in Excel for all I know.
If I load the file into my text editor (Tinn-r) I can read the material in
using the textConnection command and have no problem working with it. However
this meant that I spend an hour and a half trying to read the file and 5
minutes doing the graph I wanted. I'd like to avoid my mistake in the future
if possible.
I'm showing my last try below but the directory is almost certainly correct.
I've tried it using a full path name and, as below, after changing the active
directory.
When I try to load the file I get this:
read.csv("asp.csv", header=TRUE, sep=",")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") : cannot open file 'asp.csv': No such file or directory
If the filename is really correct, then it would appear to be a
permissions problem. Do you have read permission on that file? Try
opening it in Notepad or some other program.
If that works, then I'd suggest that you actually don't have the
filename correct. (Windows does dumb things like displaying the file
"asp.csv.txt" as "asp.csv" by default.) If you use the file.choose()
function to select the file, you'll get the right filename.
