Convert list of imputation_list_single()
objects to an imputation_list_df()
object
(i.e. a list of imputation_df()
objects's)
Arguments
- imputes
a list of
imputation_list_single()
objects- sample_ids
A list with 1 element per required imputation_df. Each element must contain a vector of "ID"'s which correspond to the
imputation_single()
ID's that are required for that dataset. The total number of ID's must by equal to the total number of rows within all ofimputes$imputations
To accommodate for
method_bmlmi()
theimpute_data_individual()
function returns a list ofimputation_list_single()
objects with 1 object per each subject.imputation_list_single()
stores the subjects imputations as a matrix where the columns of the matrix correspond to the D ofmethod_bmlmi()
. Note that all other methods (i.e.methods_*()
) are a special case of this with D = 1. The number of rows in the matrix varies for each subject and is equal to the number of times the patient was selected for imputation (for non-conditional mean methods this should be 1 per subject per imputed dataset).This function is best illustrated by an example:
imputes = list( imputation_list_single( id = "Tom", imputations = matrix( imputation_single_t_1_1, imputation_single_t_1_2, imputation_single_t_2_1, imputation_single_t_2_2, imputation_single_t_3_1, imputation_single_t_3_2 ) ), imputation_list_single( id = "Tom", imputations = matrix( imputation_single_h_1_1, imputation_single_h_1_2, ) ) ) sample_ids <- list( c("Tom", "Harry", "Tom"), c("Tom") )
Then
convert_to_imputation_df(imputes, sample_ids)
would result in:imputation_list_df( imputation_df( imputation_single_t_1_1, imputation_single_h_1_1, imputation_single_t_2_1 ), imputation_df( imputation_single_t_1_2, imputation_single_h_1_2, imputation_single_t_2_2 ), imputation_df( imputation_single_t_3_1 ), imputation_df( imputation_single_t_3_2 ) )
Note that the different repetitions (i.e. the value set for D) are grouped together sequentially.
