[Bioc-devel] Packaging a medium/large project

Hey list,

i am about to package a fairly large project. Unfortunately, the code
quality is suboptimal - it uses a lot of source() to jump between source
files:

  data <- ...

  # Do something with data
  source("R/process_data.r", local=T)

  # Do something with the results
  source("R/process_results.r", local=T)

  # Do something like this many times
  ...

Whats the best way to package something like this? My idea was to write
a slim wrapper:

  something.run <- function(data) {
    source("R/run.r")
  }

The problem now is that source() can't find the files, when executed
inside the package. What is best practice here (apart from a rewrite)?

Cheers, ushi
