Subject: Private data libraries (idea & trick)
Message-ID: <x2iu5388wk.fsf@blueberry.kubism.ku.dk>

It has been annoying me for a while that data in user areas are more
difficult to handle than those in the packages. 

Especially for beginners, it would be very handy to be able just to
say "data(mydata)", rather than
"mydata<-read.table('mydata.txt',header=T)"

What just occurred to me was that the following hack actually works:

Type

library('.',lib.loc='.')

and everything in ./data behaves as if it were in a package. 

Another interesting hack is that one can do this:

[pd@blueberry data]$ cat > file.txt
a b
1 2
3 4
[pd@blueberry data]$ cat > file.R
file<-transform(read.table('file.txt',header=T),
    b=factor(b,levels=1:4,labels=letters[1:4]))

and then from inside R, get the dataframe with factor recoding and
everything as

> data(file)
> file
  a b
1 1 b
2 3 d

Question: Should we perhaps clean this up a little and formalize it?
