Thank you Professor:
After reading in the file this is what I see:
file.label
[1] "EXAMPLE 1 â vs a.xls"
charToRaw(file.label)
[1] 45 58 41 4d 50 4c 45 20 31 20 c3 a2 20 76 73 20 61 2e 78 6c 73
Encoding(file.label)
[1] "UTF-8"
Encoding(paste("diagnostic â vs a ", file.label, ".jpg", sep = ""))
[1] "UTF-8"
But look what happens after I run your example:
charToRaw(file.label)
[1] 45 58 41 4d 50 4c 45 20 31 20 e2 20 76 73 20 61 2e 78 6c 73 (after)
[1] 45 58 41 4d 50 4c 45 20 31 20 c3 a2 20 76 73 20 61 2e 78 6c 73 (before)
The file label appears on the screen as it does above both times, but
clearly charToRaw() shows that the coding for â has changed from the
unexpected c3 a2, to the desired e2.
After running your example I now observe
Encoding(file.label)
[1] "latin1"
Again, thank you for your help.

That also works without a hitch on my box, even in vanilla 2.7.2. What
exactly is in file.label as given by
charToRaw(file.label)
Encoding(file.label)
? It should be in UTF-8, and so should
paste("diagnostic â vs a ", file.label, ".jpg", sep = "")
It looks like the latter is not being treated as UTF-8 on your system (see
what Encoding() says on its value).

Thank you, Professor Ripley:
Your example works for me too.
plot(1:10, xlab = "a", ylab = "â")
file.label <- "EXAMPLE 1 â vs a.xls"
savePlot(paste("diagnostic â vs a ", file.label, ".jpg",
sep = ""), type = "jpg")
But, if I read-in the file name using file.choose() I get the same
corrupted
output filename ( "diagnostic â vs a EXAMPLE 1 â vs a.xls.jpg" ) from my
R
routines. However, if I paste that same file.label as it is printed to
the
screen with my input routine, replacing your "foo" (as above) things work
as
they should ( "diagnostic â vs a EXAMPLE 1 â vs a.xls.jpg" ).
Furthermore,
if I again run my plotting routines after your example (like that here,
above), my routines no longer produce corrupted filenames for the saved
plots.
The trouble seems to be caused by my how I read-in the file name. Here is
a
simple example that produces a corrupted file name for the saved plot:
plot(1:10, xlab = "a", ylab = "â")
file.name <<- file.choose()
print(file.name)
file.label <<- basename(file.name)
savePlot(paste("diagnostic â vs a ", file.label, ".jpg",
sep = ""), type = "jpg")
The name of my input Excel file is "EXAMPLE 1 â vs a.xls"
The problem does not occur on R < R2.7.0
I am running R2.7.2 on a 5 year old DELL box (2 Gig RAM, 3GHz Pentium 4)
with Windows XP, and have also experienced the problem on my Thinkpad
laptop
(2 Gig, Intel Core2 Duo, 1.6GHz) running Vista.
Thank you for your counsel.

You haven't given any of the information asked for in the posting guide.
But, assuming this is Windows in CP1252 (as I believe that has been your
locale before), it works for me in current R.
plot(1:10)
file.label <- "foo"
savePlot(paste("diagnostic â vs a ", file.label, ".jpg",
sep = ""), type = "jpg")
If you are not using 2.8.0 beta or 2.7.2 patched, please check those.
This might be related to
o file.path() did not work correctly in 2.7.0 if the components
had different encodings.
(NEWS for 2.7.1).

Greetings R-wizards:
For historical reasons I have filenames with the character "â" and have
successfully used "\u00e2" in its place, with the hoped-for result on all
my
on-screen plots.
However since R2.7.0 I have trouble with savePlot() when the file name
includes that character as it does in this example:
savePlot(paste("diagnostic â vs a ", file.label, ".jpg",
sep = ""), type = "jpg")
In R2.6.0 and earlier, R would ignore a dot ('.') in the file name and
supply the extension. Since R2.7.0 if filename does include a dot,
savePlot() will not add the file type as an extension. Thus my apparent
redundancy in the file name.
The problem I have is that the example command will substitute an
unwanted
character for â, yet if I use "File, save as, jpg ... " and type in a
name
containing the troublesome character, R saves the on-screen plot with
that
character in the name with no complaints.
I have tried using iconv() with no success, as can be seen with the
following code:
file.name <- paste("diagnostic â vs a ", file.label, ".jpg", sep = "")
iconv.List <- iconvlist()
for(encoding in iconv.List) {
print(iconv(file.name, "", encoding, ""))}
So, here's the question: How can I save, with a non-interactive R
command,
an existing plot with the troublesome character in the file name?
Thanks.
