Subject: accented vowels
In-Reply-To: <mailman.282.1313131019.4449.r-sig-mac@r-project.org>
Hi,
I usually do not give second thought to accented vowels and R handles everything fine thanks to UTF8 being used in my R scripts. But today I have a problem. Accented vowels do not behave properly when they were imported into R using list.files.
Maybe this is because OS X (I'm using 10.6.8) still uses MacRoman for file names, though visually the names seem to have been read correctly into R.
An example is better than words:
sessionInfo()
R version 2.13.1 (2011-07-08)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)
locale:
[1] fr_CA.UTF-8/fr_CA.UTF-8/C/C/fr_CA.UTF-8/fr_CA.UTF-8
attached base packages:
[1] stats graphics grDevices utils datasets methods base
This does not cause problem:
a = c("1_MO2 crevettes po2crit.Rda", "1_MO2 soles S?te sda.Rda", "1_MO2 turbots po2crit.Rda"); a
[1] "1_MO2 crevettes po2crit.Rda" "1_MO2 soles S?te sda.Rda" "1_MO2 turbots po2crit.Rda"
a2 = gsub(" S?te", "S", a); a2
[1] "1_MO2 crevettes po2crit.Rda" "1_MO2 solesS sda.Rda" "1_MO2 turbots po2crit.Rda"
but if instead of creating the vector within the R script, I read it as a series of file names, the substitution does not work. I am sorry that I cannot make this a reproducible example as it requires the 3 files to exist on your computer, but you could create 3 dummy files having the same names in the directory of your choice.
don = file.path("donn?es/")
b = list.files(path = don, pattern = "1_MO2"); b
[1] "1_MO2 crevettes po2crit.Rda" "1_MO2 soles S?te sda.Rda" "1_MO2 turbots po2crit.Rda"
b2 = gsub(" S?te", "S", b); b2
[1] "1_MO2 crevettes po2crit.Rda" "1_MO2 soles S?te sda.Rda" "1_MO2 turbots po2crit.Rda"
I am puzzled and also "stuck". For now I'll modify the file name, but I need to be able to handle such names at some point.
Any advice?
thanks in advance,
Denis
