Version 0.9.3

• New functions:
  • tb() turns freq() and descr() outputs into “tidy” tibbles
  • use_custom_lang() replaces useTranslations() and triggers an Open File… dialog when no argument is supplied
    
  • define_keywords() allows defining translatable terms in GUI and optionally save the results in a csv file (through Save File… dialog)
• Deprecated functions:
  • byst() had to be dropped because of issues related to objects names; so only stby() is accepted from now on
  • useTranslations() has been replaced by use_custom_lang()
• In freq():
  • new parameter cumul allows turning on or off cumulative proportions
  • order parameter: “names”, “freq”, and “levels” values now have their counterparts “-names” (or “names-”), “-freq” and “-levels”
  • a new parameter rows has been added; it allows subsetting the output table either with a numeric vector, a character vector, or a single search string (regex)
• In ctable():
  • Added weights support
  • Added logical argument “chisq.test” to display chi-square results below the cross-tabulation table
• In dfSummary():
  • Added content specific to email addresses – valid, invalid, duplicates
• Added translations :
  • Portuguese (“pt”)
  • Turkish (“tr”)
  • Russian (“ru”)

Version 0.9.2

No changes (re-submission of 0.9.1 to CRAN)

Version 0.9.1

For users updating solely from CRAN, this is a major update. Many changes were introduced since version 0.8.8 (versions 0.8.9 and 0.9.0 were released solely on GitHub). Please refer to the README file, the two vignettes and the information below for all the details.

In this version:

• stby(), a summarytools-specific version of by(), is introduced. It is highly recommended that you use it instead of by(); its syntax is identical and it greatly simplifies the printing of the generated objects
• In dfSummary():
  • ‘max.tbl.height’ allows printing summaries in scrollable windows (useful in .Rmd when a data frame contains numerous variables)
    
  • setting ‘tmp.img.dir’ allows the inclusion of png graphs in Rmarkdown documents when using pander method in combination with arguments plain.ascii = FALSE and style = “grid”
    
  • Platform-specific png device types are used, improving image quality
    
• Several examples are added to all main functions; use the example() function to access them

Version 0.9.0

• Output translations are introduced. For instance, setting st_options(lang='fr') gives access to French translations. Spanish (‘es’) translations are also available.
• Function useTranslations() allows using custom translations; see the introductory vignette for details
  
• In descr(), the weighting variable (when used) is automatically removed from the list of variables to analyze
  
• In dfSummary(), images are processed using functions from the magick package, improving the general layout of the output tables
• Improved support for magrittr operators

Version 0.8.9

• In dfSummary():
  • Number of columns and number of duplicates added to the headings section
    
  • Integer sequences as well as UPC/EAN codes are detected and identified
    
  • Statistics for unary / binary data are simplified
    
  • Bar charts now reflect frequencies across variables
    
• In descr(), the ‘stats’ parameter accepts values “common” and “fivenum”
  
• With st_options(), setting multiple options at once is now possible; all options have their own parameter (the legacy way of setting options is still supported)
  
• More parameters can be overridden when calling print() or view() - refer to the print() method’s documentation to learn more

Two somewhat backward-compatibility breaking changes:
- The ‘omit.headings’ parameter is replaced by the more straightforward (and still boolean) ‘headings’. The former is still supported but will disappear in a future release (possibly 0.9.2)
- Row subsetting is no longer displayed in the headings section, as it was error-prone

Special thanks to Paul Feitsma for his numerous suggestions.

Version 0.8.8

• Removed extra space in dfSummary() with time objects
  
• Allowed one more value for frequency counts in dfSummary() when “[1 other value]” was displayed; this actual value is now displayed instead

Version 0.8.3

• In all functions, argument ‘split.table’ becomes ‘split.tables’ as per changes in the ‘pander’ package
  
• Argument ‘omit.headings’ added to all main functions

• Added rudimentary support for lapply() to be used with freq()
  
• Improved support for by() and with() with descr(), freq(), and ctable()

Backward-compatibility notes: in dfSummary(), parameter name ‘display.labels’ has been changed to ‘labels.col’, for consistency reasons. Also, see Notes for Version 0.6.9 about the ‘file’ parameter.

Version 0.7.0

Another GitHub-only release
- Improved alignment in cells having counts + proportions
- Updated vignette to reflect latest changes and added examples using the example datasets “exams” and “tobacco”
- dfSummary()’s last column now includes counts and percentages for both valid and missing data
- Internal change: Roxygen2 is now used to generate documentation

Version 0.6.9

In this GitHub-only release:
- Introduced ctable() for cross-tabulations
- Extended support for printing objects created using by() and/or with(): variable names, labels and by-groups are now displayed correctly
- view() is now more than just a wrapper function for the print() method; it is the function to use when printing an object created with by()
- Appending to summarytools-generated html files is now possible - Most pander options stored in summarytools objects can be overridden by print() or view()
- freq() has an new parameter, ‘order’, allowing to order rows by count rather than values
- Alignment of numbers in descr() observations table has been improved

An important change causing a minor break in backward compatibility: the ‘file’ parameter must now be used with print() or view(); its use with other functions is now deprecated.

Version 0.6.5

• Fixed a problem with dfSummary() which arose when number of factor levels exceeded max.distinct.values
  
• Improved the way dfSummary() reports frequencies for character variables
  
• Fixed problems with outputs when using weights

• Removed Bootstrap content not likely to be used
  
• Changed the way method = "browser" sends file path to browser for better cross-platform compatibility
  
• Improved results when using by()

Version 0.5

For this GitHub-only release:
- Function descr() now supports weights
- Output from what.is() has been simplified
- Other changes are transparent to the user, but make the internals more consistent across functions

Version 0.4

Added cat() functions to fully support knitr’s document generation. Also added sample datasets so that users can experiment using summarytools functions with them. freq() now supports weights.

Version 0.3

Another round of major changes

• Bringing in HTML table built with htmltools and viewable in RStudio’s Viewer
  
• Function desc() is renamed descr() (mainly to avoid conflict with plyr::desc())
  
• Argument ‘echo’ is deprecated; either display with pander or use as.table()
  
• Returned objects are now of class “summarytools” and have several attributes that are used by print.summarytools()
  • st.type : one of “freq”, “descr” and “dfSummary”
    
  • date : date at which the function was called
    
  • var.name and var.label : for freq(), and also descr() when a single vector is used
    
  • pander.args : “style”, “justify”, “plain.ascii”, “split.table”
    
• print.summarytools() has argument ‘method’ that can be one of “pander”, “viewer”, or “browser”, the last two being used to display an HTML version of the output, using Bootstrap’s css (https://getbootstrap.com)
  
• Row indexing is “detected” and reported (function .parse.arg.x() takes care of this)
  
• Rounding now only occurs at the printing stage

Version 0.2

Several major changes since version 0.1

• unistats() is now called desc()
• frequencies() is now called freq()
  
• properties() is now called prop()

• desc() can be transposed to suit one’s preferences
  
• freq() just returns a matrix-table, not a list anymore
  
• In desc() and freq(), no more argument ‘display.label’. Those are displayed automatically when present
  
• rapportools is used instead of Hmisc for variable labels
  
• Function properties() was removed for now. May be reintegrated in a future version
