laboratory

For laboratory check, you need to create the excel table like in the example.

AGELOW - number, >= number
AGEHIGH - if none, type Inf, <= number
SEX - for both sex, use |
LBTEST - What was the lab test name? (can be any convenient name for you)
LBORRES* - What was the result of the lab test?
LBNRIND* - How [did/do] the reported values compare within the [reference/normal/expected] range?
LBORNRLO - What was the lower limit of the reference range for this lab test, >=
LBORNRHI - What was the high limit of the reference range for this lab test, <=

*column names without prefix or postfix

dates

For dates check, you need to create the excel table like in the example.

MINUS, PLUS, VISITDY - parameter of a timeline
VISITNUM - clinical encounter number, parameter for function e.g. contains(num_visit)
VISIT - protocol-defined description of a clinical encounter (can be any convenient name)
STARTDAT - column name of start date, with postfix or prefix
STARTVISIT - can be any convenient name of start date for you
IS_EQUAL - Boolean data type(T/F) to check date equality within a visit
EQUALDAT - column name for check date’s equality, with postfix or prefix

dplyr::contains - A function, which select necessary visit or event e.g. dplyr::start_with, dplyr::contains. It works like df %>% select(contains("E1")). You also can use dplyr::start_with, works like df %>% select(start_with("V1"))

dplyr::matches - A function, which select dates from necessary visit e.g. dplyr::matches, dplyr::contains. It works like visit_one %>% select(contains("DAT")), default: dplyr::contains()

rename

Function to rename the dataset, using crfs.

rename_dataset("./crfs", "old_name", "new_name", 2)

“./crfs” - path to crfs
“old_name” - variable for names in the dataset, without postfix or prefix
“new_name” - variable for necessary names, names should be unique
2 - a position of a sheet in the excel document, where dmtools can find “old_name” and “new_name”
