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 Sète sda.Rda", "1_MO2 turbots
po2crit.Rda"); a
[1] "1_MO2 crevettes po2crit.Rda" "1_MO2 soles Sète sda.Rda" "1_MO2 turbots
po2crit.Rda"
a2 = gsub(" Sète", "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("données/")
b = list.files(path = don, pattern = "1_MO2"); b
[1] "1_MO2 crevettes po2crit.Rda" "1_MO2 soles Sète sda.Rda" "1_MO2 turbots
po2crit.Rda"
b2 = gsub(" Sète", "S", b); b2
[1] "1_MO2 crevettes po2crit.Rda" "1_MO2 soles Sète 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
