reprex has a website: http://reprex.tidyverse.org. It includes a contributed article from @njtierney (#103).
reprex() gains several arguments and many arguments can now be controlled via an option, in case a user wants their own defaults.
reprex_selection() add-in reprexes the current selection, with venue controlled by the option
reprex.venue. It can be handy to bind to a keyboard shortcut (#84 @hadley).
If reprex can’t write to the user’s clipboard (e.g. on RStudio server or Unix-like systems lacking xclip or xsel), it offers to open the output file for manual copy.
These look like
reprex(..., arg = opt(DEFAULT), ...) in the help file. This is shorthand for
arg = getOption("reprex.arg", DEFAULT), i.e. the option
reprex.arg is consulted and, if unset, the documented default is used. Allows user to define their own default behaviour (#116).
advertise: toggles inclusion of a footer that describes when and how the reprex was created, e.g., “Created on 2017-11-16 by the reprex package (v0.1.1.9000)”. Defaults to
style: requests code restyling via the newly-Suggested styler package. styler can cope with tidyeval syntactical sugar, e.g.
df %>% group_by(!! group_var). Defaults to
tidyverse_quiet: affords control of the startup message of the tidyverse meta-package. Defaults to
TRUE, i.e. suppresses the message (important special case of #70, #100).
std_out_err: appends output sent to stdout and stderr by the reprex rendering process. This can be necessary to reveal output if the reprex spawns child processes or has
system()calls. Defaults to
render: determines if the reprex is actually rendered or just returns after producing the templated
.Rfile. For internal testing.
Line wrapping is preserved from source via a Pandoc option (#145 @jimhester, #175).
venue = "gh" now targets CommonMark as the standard for GitHub Flavored Markdown (#77).
venue = "so" has appropriate whitespace at the start.
venue = "ds" is a new value, corresponding to https://www.discourse.org, which is the platform behind community.rstudio.com. This is currently just an alias for the default
"gh" GitHub venue, because the formatting appears to be compatible. Adding the
"ds" value so Discourse can be documented and to guard against the possibility that some formatting is actually unique.
keep.source option is set to
TRUE when rendering the reprex, so reprexes involving srcrefs should work (#152).
The default value for knitr’s
upload.fun is now set according to the venue. It is
knitr::imgur_upload() for all venues except
"r", where it is
The HTML preview should appear in the RStudio Viewer more consistently, especially on Windows (#75 @yutannihilation).
More rigorous use of UTF-8 encoding (#76 @yutannihilation).
Expression input handling has been refactored. As a result, formatR is no longer Suggested. Trailing comments – inline and on their own line – are also now retained (#89, #91, #114, @jennybc and @jimhester).
Custom prompts are now escaped when used in regexes (#98, #99 @jimhester). Embedded newlines are now escaped.
This was a non-functioning release created by CRAN maintainers by commenting out lines of code relating to the clipboard.
outfile = NA causes outfiles to be left in working directory. Filenames will be based on the
input file, if there was one.
reprex() strips any leading prompts from input code.
venue = "R" (or
"r") can be used to get an R script back, augmented with commented output.
comment argument added to specify prefix for commented output.
Added an RStudio addin, accessed via “Render reprex”.
input argument to
reprex() and friends handles code as string, character vector, or file path.
The reprex is rendered via
callr::r_safe() and is thus run in a clean, separate R process, eliminating any leakage of objects or loaded packages to/from the calling session.
reprex()gains optional arguments
opts_knit, taking named list as input, in order to supplement or override default knitr chunk and package options, respectively. (#33)
upload.funargument unnecessary, so it’s gone. The
upload.funoption defaults to
knitr::imgur_upload, which means figures produced by the reprex will be uploaded to imgur.com and the associated image syntax will be put into the Markdown, e.g.
!(http://i.imgur.com/QPU5Cg9.png). (#15 @paternogbc)
reprex() arguments has changed.
reprex() gains the
si argument to request that
sessionInfo() be appended to reprex code (#6 @dgrtwo). When
si = TRUE and
venue = "gh" (the default), session info is wrapped in a collapsible details tag. See an example (#55).
Reprex code can be provided as an R expression. (#6 @dgrtwo, #35)
