v0.1.0

lighthouse.codebook 0.1.0

• New function cb_summarize_text() returns a summary of text variables including
  unique values, frequencies for the most common values, and missing value information.
  A tab including this information is now included in workbooks created by cb_write().

• In workbooks produced by cb_write(), variable names on the Overview sheet are
  now hyperlinked to corresponding rows on summary tabs and vice versa. This can
  be turned off by setting hyperlinks to FALSE.

• The .split_var_labels argument to cb_create() and variants splits variable
  labels with a common prefix into separate columns. For example, given a set of
  variable labels that all begin with "Select all that apply: ", the default behavior
  is:

  Name	Label
  colors1	Select all that apply: Red
  colors2	Select all that apply: Green
  colors3	Select all that apply: Blue
  colors4	Select all that apply: Orange

  ...but specifying .split_var_labels = colors1:colors4 yields:

  Name	Label Stem	Label
  colors1	Select all that apply:	Red
  colors2	Select all that apply:	Green
  colors3	Select all that apply:	Blue
  colors4	Select all that apply:	Orange

  Multiple sets of variables with common prefixes can be specified by passing a
  list of tidyselect expressions.

• cb_create() and variants now return more general type information (e.g., "date-time"
  rather than "POSIXct, POSIXt") when .include_types is TRUE (the default).
  Detailed class information can be requested by setting .include_r_classes to TRUE.

• n for each subgroup are now included in decked headers for grouped summaries.

• In cb_write(), changed detail_missing argument from logical to options "if_any_user_missing",
  "yes", and "no".

• cb_summarize_numeric(), cb_summarize_categorical(), and cb_summarize_text()
  now return NULL when there are no variables of the relevant type, with an optional
  warning controlled by the .warn_if_none argument.

• Categorical, numeric, and/or text summary tabs are now omitted when there are
  no variables of the relevant type.

• In cb_create() and variants, changed .rmv_html and .rmv_line_breaks arguments
  to logical rather than tidyselect.
