Quick setup

install.packages("remotes")
# remotes::install_github("brry/rskey")
install.packages("rskey", repos = c('https://brry.r-universe.dev', 'https://cloud.r-project.org'))
rskey::setKeyboardBindings()
# moves existing shortcuts to backup file

• F3: structure of an object - str(selected_code)
• F4: head of an object - head(selected_code)
• F5: tail of an object - tail(selected_code)
• F6: View an object - View(selected_code)
• F7: funSource of an object - funSource(selected_code)
• F8: summary of an object - summary(selected_code)
• F9: dim of an object - dim(selected_code)
• F10: class of an object - class(selected_code)
• F11: plot an object - plot(selected_code, las=1)
• F12: histogram of an object - hist(selected_code, col="moccasin", breaks=50, las=1)
• also sets:
• CTRL/CMD + Y: redo (by removing it from paste last yank)
• CTRL + H: set working dir to active document
• ALT + S: quarto render document
• ALT+W, or control+W: toggle line wrapping (depending on OS)
• CTRL/CMD + Shift + Y: score for course
• for my convenience sets:
• CTRL/CMD + R: add \rcode{text} around text in an Rnw document
• CTRL/CMD + K: knit Rnw file to pdf rskey::bknit2pdf (set to knitDocument if wanted)
• removes:
• CTRL/CMD + Shift + D: roxygenizePackage to enable duplicate text/line inside a package
• CTRL/CMD + Shift + K: knitDocument as I prefer CTRL/CMD + K

selectively (un)set some manually:

• Rstudio - Tools - Modify Keyboard Shortcuts
• click on an addin shortcut field and press the desired key combination

label the keyboard if wanted :)

funSource

funSource provides an easy option to open the source code of a function in a browser window.
Through github, there are nice syntax highlighting and search options.

find package

funSource(someFunction) tries to find the corresponding package to the input function.
You can also explicitly request funSource("somePackage::someFunction").
This works even if the package is not installed (in which case you do need the quotation marks).

open urls

In the default browser, it opens the first link if it exists, the second if not:

• github.com/cran/somePackage/blob/master/R/someFunction.R (or .r file)
• github.com/search?q=someFunction function repo:cran/somePackage+path:R

The second link is a github search query needed when a function is defined in a file with a different name.
Functions in the base R packages will be searched in the wch/r-source/src/library repo.

limits

Currently, the funSource-initiated github search doesn't find names or dimnames in base R. Any idea to solve this kind of limitation is welcome!

origin

funSource is imported from berryFunctions.
The selectobject code idea is from digital-dharma/RStudioAddIns).
