Must be obvious but not to me : problem with regular expression
Hi,
I have a vector called nfichiers of 138 names of file whose extension is .P0
or P1 ... to P8.
The script is not the same when the extension is P0 or P(1 to 8).
Examples of file names :
[128] "Output0.P0"
[129] "Output0.P1"
[130] "Output0.P2"

Problem with save or/and if (I think but maybe not ...)
...st want to copy the new data in a
database in MySQL (which already contains the previous data).
So the first task is to compare the list of the files in the directory
(object : rfichiers) to the list of the files already saved (object :
tfichiers). The list containing the new files is then given by
nfichiers<-setdiff(rfichiers, tfichiers).
It sounds easy ...

But I think there must be another way to solve it taking advantages of the R
language (which I don't master at all), that is with less "if" tests.
To sum up :
nfichiers is a list of files (with .P0 or .Px (x>0) extension) I have to
copy to a database.
nfichiers can also be "0" if there is no file to copy
p0fichiers is the list of files having the .P0 extension if there are such
files to copy
And p0fichiers can also be "0" if there are only ....
