Hi R users,

I apologize for a seemingly trivial question, but I felt this forum would be
the best place to seek advice.

I have been an R user for a year now, but I am limited to using R and its
various contributed packages. I strongly feel that users of a free and open
source software tool must eventually provide development expertise.

I am aware of the extensive documentation available on the R project page
regarding Internals, Language definitions and the like, but I would like to
find tutorials on R development, much the same way as there are tutorials
for the use of R in statistics and data analysis.

Information on Book titles, online sources, etc that you maybe aware of
which could allow a user of R to also develop R (packages, improvise on
functions, etc) would be much appreciated.

For example, I have used the adf.test in package 'tseries' but the test
assumes a certain form the the time series process. There are 3 forms in
literature, and the other 2 are not used. I would like to modify the
adf.test to incorporate the other two forms as well.

Thanks
Harsh Singhal
