在R包中包含数据集

Question

This question may seem pretty naive and I bag your patience.

I have saved extension.RData and documented it in extension.R . Both of them are saved in /data folder of the R package I am developing.

As I close RStuidio and reload the package, however, I cannot call the data until I execute one of the functions, devtools::document() or devtool::load_all() . Does this suggest that my dataset is not in memory of the package? How could I not to execute devtools every time I start working on the package?

Thank you very much.

As I have understood, you just created files extension.RData , extension.R (with documentation) in your project directory. However, this is not enough for RStudio to be able to reach your data. You have to install the package by running devtools::install() or clicking 'Build & Reload' button on 'Build' tab of RStudio.

Edit : Putting extension.R into R folder solves the problem.
