Source: R/pq_index.R

pq_index creates a sector/industry index using the method of weighted geometric mean, based on a set of data and corresponding weights.

pq_index(dt, x = "close|value", w = "cap_total", base_value = 1,
  base_date = NULL, name = NULL)

Arguments

dt

a list/dataframe of time series dataset
x

the name of column to create index. Default is 'close|value'
w

the name of weights column. Default is 'cap_total'. If x is not available or is NULL, then using equal weights.
base_value

the base value of index. Default is 1.
base_date

the base date of index. Default is the minimum date.
name

the name of index. Default is NULL, then using 'index'.

Examples

# \donttest{
# Example I bank share index
library(data.table)
data(banks)

# creating index
bank_index = pq_index(banks, x='close', w='cap_total')
# pq_plot(bank_index)

# }
