rumba: Apply several functions to the same column

In romainfrancois/dance: Tibble Dancing

Description

Apply several functions to the same column

Usage

rumba(.var, ..., .tbl = get_tbl(), .name = NULL, .env = caller_env())

zumba(.var, ..., .tbl = get_tbl(), .name = NULL, .env = caller_env())

Arguments

.var	A variable specified as in dplyr::pull()
...	list of functions or formulas using . to refer to the column
.tbl, .env	data frame to get columns from and caller environment. Most of the time, you don't need to set these
.name	glue::glue() model to name the created columns. The model can use : {fun} to refer to the function name {idx} to refer to the index of the function with the given list {var} to refer to the selected name The default uses "{fun}" is the ... list is named, and "fn{idx}" otherwise

Value

• rumba() returns a spliced list of formulas suitable for the ... of a choreography() based dance, e.g. tango(), samba(), jive()

• zumba() returns a single formula that packs the results

Examples

g <- group_by(iris, Species)

# ---- tango()
g %>%
  tango(rumba(Sepal.Length, mean = mean, median = median))

# select the first column, control the result names
# with the glue() model
g %>%
  tango(rumba(1, mean = mean, median = median, .name = "{var}_{fun}"))

g %>%
  tango(Sepal.Width = zumba(Sepal.Width, mean = mean, median = median))

# ---- jive()
g %>%
  jive(
    rumba(Sepal.Width, five = fivenum, quantile = quantile)
  )
