Set factor order of given variable. If variable_order is supplied, only factors in variable_order will be kept and re-factored. Other variables would be depleted.

Description

Set factor order of given variable. If variable_order is supplied, only factors in variable_order will be kept and re-factored. Other variables would be depleted.

Usage

sp_set_factor_order(
  data,
  variable,
  variable_order = NULL,
  order_data_frame_by_this_variable_order = F,
  filter_unexist_factor = T,
  rename_levels = F
)

Arguments

data	A data matrix
variable	One column name of data matrix
variable_order	Expected order of data[[variable]].
order_data_frame_by_this_variable_order	Return ordered dataframe by this order. Please remember that only keep the last order if applying multiple order operation.
filter_unexist_factor	Filter un-exist factors.
rename_levels	Rename old levels to new levels. Default False.

Value

A data frame

Examples

data <- data.frame(A=letters[1:4], B=letters[1:4])
data
data = sp_set_factor_order(data,'A')
data$A
data = sp_set_factor_order(data,'B',c('c','d','b','a'))
data$B
data = sp_set_factor_order(data,'B',c('c','d','a'))
data$B
