Creating a package in R using RStudio

Question

I've created a bunch of files:

• init.r
• auth.r
• class.r
• modules/status.r
• modules/mgmt.r
• modules/core.r
• modules/mcf.r

The source of the init.r file is:

# initiation of package

# include libraries
library(RCurl);
library(rjson);

# include files
source('auth.r');
source('class.r');

# extend class
source('modules/status.r');
source('modules/mgmt.r');
source('modules/core.r');
source('modules/mcf.r');

How do I go about creating a package out of this? The init.r file obviously needs to be initiated first.

Answer 1

Start with following the steps in this video:

Build an R Package in under 2 minutes with RStudio

Then read more about RStudio's Package Development feature, and also Hadley Wickam's Package basics.

Answer 2

See Writing R Extensions for the process of making a package. You might want to use package.skeleton to get started.

But essentially,

• get rid of your init.r file,
• put all your other .R files in the R directory
• write Depends: RCurl, rjson in your DESCRIPTION file.
