# RStudio overrides `history()`, `loadhistory()` and `savehistory()`, 
# so they work somewhat differently than on the console version of R.
# This saves the current history to a temporary file then reads the last
# line of it (or more depending on the `n` argument)
#
# It does not handle multi-line commands, which would be more tricky to handle...

my-packages

• Have a look around the files here. Where are the R scripts? What are the directories data and figs for? Do the names and structure help you find things?
• Open each R script, finish it, and run it. Remember to restart R as you go, so you are certain each file is complete, i.e. data flows through explicit write/read, not the global workspace.
  • R/01_write-installed-packages.R
  • R/02_wrangle-packages.R
  • R/03_barchart-packages-built.R
• It's OK if you don't finish! We can keep working on this later.
• If you finish quickly, write an R script to run the whole analysis and, perhaps, another script that does a make clean style reset.

#' Which libraries does R search for packages?

# try .libPaths(), .Library


#' Installed packages

## use installed.packages() to get all installed packages
## if you like working with data frame or tibble, make it so right away!
## remember to use View() or similar to inspect
