package ocaml-r

  1. Overview
  2. Docs

Environment is the type of a module containing all necessary informations and data in order to set up the R interpreter properly.

val name : string

This is the name of the first argument of argv for R. Mandatory, otherwise libR.so segfaults immediately.

val options : string list

Other command line options passed to the libR.so library when initialising R.

  • see R reference manual

    File refman.pdf, page 452, section intitled 'Startup - Initialization at Start of an R Session' for details about the most important command line options.

val signal_handlers : bool

If set to false, asks R not to install its signal handlers. I've been experiencing weird issues with R signal handlers, since, for instance, a SIGSEGV is sometimes caught by libR.so, and R then asks whether or not you want to save your workspace, et ceteræ... By default, set to false.

val env : (string * string) list

These are environment variables that needs to be set before initialising the R interpreter. In the Standard module, these values are determined when the binding itself is compiled.

val packages : string list option

Packages loaded on startup. If set to None, load the usual standard library. Otherwise, if set to Some p, load packages p in place of the standard library. In the Standard module, this is set to Some [].
