Loads data into memory based on study directory and one or more file names

Usage

load_data(
  sub_dir = NULL,
  file_names,
  use_wd = FALSE,
  prefer_sas = FALSE,
  reduce_memory_footprint = TRUE
)

Arguments

sub_dir

A relative directory/folder that will be appended to a base path defined by Sys.getenv("RXD_DATA"). If the argument is left as NULL, the function will load data from the working directory getwd().

file_names

Study file or file_names name(s) - can be a vector of strings. This is the only required argument.

use_wd

for "use working directory" - a flag used when importing local files not on NFS - default value is FALSE

prefer_sas

if TRUE, imports .sas7bdat files first instead of .RDS files

reduce_memory_footprint

[logical(1)]

If TRUE, character variables are mapped into factors and floating-point variables are mapped into integers, as long as the conversion does not lead to loss of precision.

If FALSE, this function respects the original types returned by the underlying calls to base::readRDS and haven::read_sas.

Value

a list of dataframes

Examples

if (FALSE) { # \dontrun{
test_data_path <- "../inst/extdata/"
data_list <- load_data(
  sub_dir = test_data_path,
  file_names = "dummyads2",
  use_wd = TRUE
)
} # }
