Description

Utility function to compare data type of study data with those defined in metadata

Usage

util_compare_meta_with_study(
  sdf,
  mdf,
  label_col,
  check_convertible = FALSE,
  threshold_value = 0,
  return_percentages = FALSE,
  check_conversion_stable = FALSE
)

Value

for return_percentages == FALSE: if check_convertible is FALSE, a binary vector (0, 1) if data type applies, if check_convertible is TRUE`` a vector with the states 0, 1, 2, 3: 0 = Mismatch, not convertible 1 = Match 2 = Mismatch, but convertible 3 = Mismatch, convertible, but with issues (e.g., loss of decimal places) for return_percentages == TRUE`: a data frame with percentages of non-matching datatypes according, each column is a variable, the rows follow the vectors returned by util_check_data_type.

Arguments

sdf

the data.frame of study data

mdf

the data.frame of associated static metadata

label_col

variable attribute the name of the column in the metadata with labels of variables

check_convertible

logical also try, if a conversion to the declared data type would work.

threshold_value

numeric from=0 to=100. percentage failing conversions allowed if check_convertible is TRUE.

return_percentages

logical return the percentage of mismatches.
