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.

Subject: Re: [R] trouble with character \u00e2
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).
