General

Changes to functions

  • frq() now also prints frequencies of logical conditions, e.g. how many values are lower or greater than a certain threshold.
  • frq() gets a min.frq-argument, indicating the minimum frequency for which a value will be shown in the output.
  • descr() gets a show argument to show selected columns only.
  • descr() gets a file-argument to write the output as HTML file.
  • var_rename() now also accepts a named vector with multiple elements as ellipses-argument.

Bug fixes

  • Fixed erroneously warning in de_mean().
  • merge_df() now removes columns with identical column names inside a data frame before merging, to avoid errors.
  • Fixed issue when printing character vectors in frq(), where first element was empty, and vectors were not provided as data frame argument.
  • Fixed issue in word_wrap() when processing expressions.
  • Fixed issue in rec() with token rec = "rev", when reversing labelled vectors with more value labels than values.

sjmisc 2.8.1 2019-06-17

General

  • Revised docs.

Bug fixes

  • Fixed issue with forthcoming update of the rlang package.

sjmisc 2.7.8 2019-03-12

General

  • Reduce package dependencies.
  • str_pos() was renamed into str_find().
  • New package-vignette Recoding Variables.

New functions

Changes to functions

  • is_whole() now automatically removes missing values from vectors.
  • is_empty() now also checks lists with only NULL-elements.

Bug fixes

  • Better handling of factors in merge_imputations(), which previously could result in NA-values when merging imputed values into one variable.
  • Fix issue in is_empty() in case the vector had non-missing values, but first element of vector was NA.
  • Fixed bug in frq() for grouped data frame, when grouping variable was a character vector. In this case, group titles were mixed up.

sjmisc 2.7.7 2019-01-02

New functions

  • tidy_values() to “clean” values (i.e. remove special chars) of character vectors or levels of factors.
  • add_id() to quickly add an ID variable to (grouped) data frames.

Changes to functions

  • frq() gets a show.na-argument, to (automatically) show or hide the information for NA-values from the output.
  • The weights-argument in frq() now also accepts vectors, and is not limited to variable names. Note that these vectors must be part of a data frame.

  • Improved performance for group_str().
  • var_rename() now supports quasi-quotation (see Examples).
  • row_sums() and row_means() now return the input data frame when this data frame only had one column and no row means or sums were calculated. The returned data frame still gets the new variable name defined in var.

General

  • Reduce package dependencies.

New functions

  • de_mean() to compute group-meaned and de-meaned variables.
  • add_variables() and add_case() to add columns or rows in a convenient way to a data frame.
  • move_columns() to move one or more columns to another position in a data frame.
  • is_num_chr() to check whether a character vector has only numeric strings.
  • seq_col() and seq_row() as convenient wrapper to create a regular sequence for column or row numbers.

Changes to functions

  • descr() gets a weights-argument, to print weighted descriptive statistics.
  • The n-argument in row_means() and row_sums() now also may be Inf, to compute means or sums only if all values in a row are valid (i.e. non-missing).
  • Argument weight.by in frq() was renamed into weights.
  • frq() gets a title-argument, to specify an alternative title to the variable label.

Bug fixes

  • round_num() preserves data frame attributes.
  • frq() printed frequencies of grouping-variable for grouped data frames, when weights was not NULL.

sjmisc 2.7.4 2018-08-04

New functions

Changes to functions

  • set_na() now also replaces different values per variable into NA.
  • Changed behaviour of row_sums() and missing values. row_sums() gets a n-argument and now computes row sums if a row has at least n non-missing values.

sjmisc 2.7.3 2018-06-20

General

  • A test-suite was added to the package.
  • Updated reference in CITATION to the publication in the Journal of Open Source Software.

New functions

Changes to functions

  • ref_lvl() now also accepts value labels as value for the lvl-argument. Additionally, ref_lvl() now also works for factor with non-numeric factor levels and simply returns relevel(x, ref = lvl) in such cases.

Bug fixes

  • Fixed encoding issues in rec() with direct labelling for certain locales.

sjmisc 2.7.2 2018-05-04

New functions

  • round_num() to round only numeric values in a data frame.

General

  • Improved performance for merge_df(). Furthermore, add_rows() was added as alias for merge_df().
  • merge_df() resp. add_rows() now create a unique id-name instead of dropping the ID-variable, in case id has the same name of any existing variables in the provided data frames.
  • Improved performance for descr() and minor changes to the output.

Support for mids-objects (package mice)

Following functions now also work on mids-objects, as returned by the mice()-function:

Changes to functions

  • The weight.by-argument in frq() now should be a variable name from a variable in x, and no longer a separate vector.

Bug fixes

  • descr() does not work with character vectors, so these are being removed now.

sjmisc 2.7.1 2018-03-25

General

  • Fix typos and revise outdated paragraphs in vignettes.

New functions

The recoding and transformation functions get scoped variants, allowing to select variables based on logical conditions described in a function:

Changes to functions

  • std() gets a new robust-option, robust = "2sd", which divides the centered variables by two standard deviations.
  • Slightly improved performance for set_na().

Bug fixes

  • frq() now removes empty columns before computing frequencies, because applying frq() on empty vectors caused an error.
  • empty_cols() and empty_rows() (and hence, remove_empty_cols() and remove_empty_rows()) caused an error for data frames with only one column resp. row, or if x was a vector and no data frame.
  • frq() now removes missing values from input when weights are applied, to ensure that input and weights have same length.

  • Argument groupcount in split_var(), group_var() and group_labels() is now named n.
  • Argument groupsize in group_var() and group_labels() is now named size.
  • frq() gets a revised print-method, which does not print the result to console when captured in an object (i.e., x <- frq(x) no longer prints the result).
  • frq() no longer prints (redundant) labels for factors w/o value label attributes.
  • frq() adds information about the variable type in the table caption (only for variables with variable labels).
  • frq() adds information about groups when printing grouped, non-labelled variables.

  • to_character() now preserves variable labels.

sjmisc 2.5.0 2017-06-12

  • col_count() to count specific values in a data frame per variable.
  • str_start() and str_end() to find starting and end indices of patterns inside strings.

Changes to functions

  • The output for frq() now always includes a NA-row, but no longer prints a value for the NA-row.
  • merge_imputations() gets a summary-argument to plot a graphical summary of the quality of the merging process.

Bug fixes

  • add_columns() and replace_columns() crashed R when no data frame was specified in ...-ellipses argument.
  • descr() and frq() used wrong variable labels when processing grouped data frames for specific situations, where the grouping variable had no sequences values.
  • descr() did not work for large data frames, because internally, because psych::describe() switched to fast mode by default then (removing columns from the output).
