read_all_xpt {EDCimport} | R Documentation |
Read all .xpt
files in a directory
Description
Read all .xpt
files in a directory (unzipped TrialMaster archive).
If 7zip
is installed, you should probably rather use read_trialmaster()
instead.
If a procformat.sas
file exists in the directory, formats will be applied.
Usage
read_all_xpt(
path,
...,
format_file = "procformat.sas",
clean_names_fun = NULL,
split_mixed = FALSE,
extend_lookup = TRUE,
datetime_extraction = "guess",
verbose = getOption("edc_read_verbose", 1),
directory = "deprecated",
key_columns = "deprecated"
)

Value
a list containing one dataframe for each .xpt
file in the folder, the extraction date (datetime_extraction
), and a summary of all imported tables (.lookup
).
Format file
format_file
should contain the information about SAS formats. It can be either
a
procformat.sas
file, containing the whole PROC FORMATor a data file (.csv or .sas7bdat) containing 3 columns: the SAS format name (repeated), each level, and its associated label. Use
options(edc_var_format_name="xxx", edc_var_level="xxx", edc_var_label="xxx")
to specify the names of the columns.
