ea1c | R Documentation |
The function ea1c produces eA1C values in a tibble object.
ea1c(data)
data |
DataFrame object with column names "id", "time", and "gl", or numeric vector of glucose values. |
A tibble object with 1 row for each subject, a column for subject id and a column for eA1C values is returned. NA glucose values are omitted from the calculation of the eA1C.
eA1C score is calculated by (46.7+mean(G))/28.7
where G is the vector of Glucose Measurements (mg/dL).
If a data.frame object is passed, then a tibble object with two columns: subject id and corresponding eA1C is returned. If a vector of glucose values is passed, then a tibble object with just the eA1C value is returned. as.numeric() can be wrapped around the latter to output just a numeric value.
