net: Add subtotal to a set of categories

Description

'subtotal' adds subtotal to set of categories, 'net' replaces categories with their net value. If you provide named arguments then name will be used as label for subtotal. In other case labels will be automatically generated taking into account arguments 'new_label' and 'prefix'. Note that if you provide overlapping categories then net and subtotals will also be overlapping. 'subtotal' and 'net' are intended for usage with cro and friends. 'tab_subtotal_*' and 'tab_net_*' are intended for usage with custom tables - see tables. There are auxiliary functions 'hide' and 'unhide'. 'hide' is used with 'subtotal' when you need to leave only subtotal for some specific items. And 'unhide' is used with 'net' when you want to show items for some nets. See examples.

Usage

net(
  x,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last"),
  add = FALSE
)
subtotal(
  x,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last"),
  add = TRUE
)
tab_net_cells(
  data,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last")
)
tab_net_cols(
  data,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last")
)
tab_net_rows(
  data,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last")
)
tab_subtotal_cells(
  data,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last")
)
tab_subtotal_cols(
  data,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last")
)
tab_subtotal_rows(
  data,
  ...,
  position = c("below", "above", "top", "bottom"),
  prefix = "TOTAL ",
  new_label = c("all", "range", "first", "last")
)
hide(category)
unhide(category)

Value

multiple response set or list of the multiple response sets

Arguments

x

variable, list, data.frame or multiple response set

...

list of categories for grouping. It can be numeric vectors (for example, 1:2), ranges (for example, 4 greater(5)). If an argument is named then this name will be used as label for subtotal.

position

position of the subtotal or net relative to original categories. "below" by default. One of the "below", "above", "top", "bottom". "top" and "bottom" place nets and subtotals above or below all other categories. For nets "below" and "above" have no difference because original categories are removed.

prefix

character, "TOTAL " by default. It is a prefix to automatically created labels for nets and subtotals.

new_label

how we will combine original values for automatically generated subtotal labels. Possible values are "all", "range", "first", "last". "all" collapse all labels, "range" take only first and last label,

add

logical. Should we add subtotal to categories or replace categories with a net?

data

intermediate table. See tables.

category

category (numeric vectors, ranges, criteria) which you want to 'hide' or 'unhide'.

Examples

ol = c(1:7, 99)
var_lab(ol) = "Liking"
val_lab(ol)  = num_lab("
                     1 Disgusting
                     2 Very Poor
                     3 Poor
                     4 So-so
                     5 Good
                     6 Very good
                     7 Excellent
                     99 Hard to say
                     ")
                     
cro(subtotal(ol, BOTTOM = 1:3, TOP = 6:7, position = "top"))
# example with hide
cro(subtotal(ol, TOP1 = hide(7), TOP2 = hide(6:7), TOP3 = 5:7, BOTTOM = 1:3, position = "top"))
# autolabelling
cro(subtotal(ol, 1:3, 6:7))
# replace original codes and another way of autolabelling
cro(net(ol, 1:3, 6:7, new_label = "range", prefix = "NET "))
# unhide
cro(net(ol, 1:3, unhide(6:7), new_label = "range", prefix = "NET "))
# character variable and criteria usage
items = c("apple", "banana", "potato", "orange", "onion", "tomato", "pineapple")
cro(
    subtotal(items, 
             "TOTAL FRUITS"     = like("*ap*") | like("*an*"), 
             "TOTAL VEGETABLES" = like("*to*") | like("*on*"), 
             position = "bottom")
)
