Usage
add_sampling_variances(
fred_data,
es_value_columns = c("es_original", "es_replication"),
N_columns = c("n_original", "n_replication"),
vi_columns = c("vi_original", "vi_replication")
)
Arguments
- fred_data
FReD dataset
- es_value_columns
Character vector of column names with correlation values
- N_columns
Character vector of column names with sample sizes
- vi_columns
Character vector of target columns for sampling variances
Value
FReD dataset with additional columns for sampling variances (metafor's vi)
