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.
