ip_create_seed: Create initial dataframe of all unique target series.

In ryantimpe/ipfitr: Iterative Proportion Fitting for the Tidyverse

Description

Create initial dataframe of all unique target series. Essentially expand.grid() for the tidyverse.

Usage

ip_create_seed(tars, names.exclude = c("value"), value.set = 1,
  value.name = "value", override.warning = FALSE)

Arguments

tars	A list of data frames containing series to expand.
names.exclude	Vector of names of series to exclude from the data frame creation.
value.set	Single number or vector of numbers to initialize the seed value.name.
value.name	Name of series in the data frame containing value.set.

Value

A data frame containing one row for each combination of the data frame series. The series in the first tar data frame vary fastest. The columns names match names supplied in each of the tar data frames.

Examples

tar1 <- data.frame(x = letters[1:2], value = runif(2))
tar2 <- data.frame(y = letters[3:5], value = runif(3))
ip_create_seed(list(tar1, tar2))
