Hi helpeRs,
I have inherited a set of data files that use the file system as a
sort of poor man's database, i.e., the data files are nested in
directories that indicate which city they come from. For example:
dir.create("deleteme")
for(i in paste("deleteme", c("New York", "Los Angeles"), sep="/")) {
dir.create(i)
for(j in paste("data", 1:2, ".csv", sep="")) {
write.csv(data.frame(x=1:10), file=paste(i, j, sep="/"))
}
}
list.files("deleteme", recursive=TRUE)
What I want to end up with is
x city wave
1 New York 1
1 Los Angeles 1
1 New York 2
1 Los Angeles 2
I've started writting a simple function to do this, but it seems like
a common situation and I'm wondering if there are any packages or
functions that might make this easier.
Thanks!
Ista
