create environments contain a set of data frames filtered for each population

Description

create environments contain a set of data frames filtered for each population

Usage

create_popn_envir(
  data_names,
  popn,
  subjid_string = "subjid",
  rm_from_frame = TRUE,
  frame = parent.frame(),
  verbose = options()$verbose
)

Arguments

data_names	a character vector of the key data frames to be filtered
popn	a data frame one-row per partipant a subjid varaibel and a column for each population indicating if a participant belongs to the population. The names of the variables must match up to the values in meta_table$Population.
subjid_string	the character naming the column used in each data frame from data_names and popn, to identify the subjid.
rm_from_frame	a logical indicating if the data sets shoudl be removed from the frame environment
frame	the frame in which the original list of data sets are found, and in which the new environments will be contianed.
verbose	logical to print information on changes to the global environment or external files. Defaults to options()$verbose.

Details

Now to use the data frames defined above in data_names you have to either directly call attach(safety), for example orr lookup with attach_pop(1.01) for a table number. There are separate R environments made for each of the populations in population & population_title be careful to use detach(safety) - this is automated with write_table() and write_ggplot()
