Randomizer

Uses ras.ran_series() to create a series of groups with randomly sampled observations. Observations are distributed such as that there are no repeated entries between groups/within a series. Number of groups in the series is calculated as length(master_list) divided by group_size, rounded up to nearest integer. If an observation can not be found (for example because the groups can not be filled evenly) an error message is printed to the console and N/A inserted instead. If write = TRUE will write the series to a comma delimited .csv file (excel?).

Usage

ras.Randomizer(
  compound_list,
  group_size,
  series = 1,
  write = FALSE,
  fileName = NULL
)

Arguments

compound_list

A character vector with observations/compound names

group_size

Integer of how many observations to attempt to place in each group

series

Number of series to make

write

Default FALSE. If set to TRUE will write series to a .xlsx file

fileName

Default NULL. Name of file. Automatically appended with .xlsx

Value

List of data frames
