make_master_table {LongDat}

Create input master table from metadata and feature tables for longdat_disc() and longdat_cont()

Description

Create input master table from metadata and feature tables for longdat_disc() and longdat_cont()

Usage

make_master_table(
  metadata_table,
  feature_table,
  sample_ID,
  individual,
  keep_id = FALSE
)

Arguments

metadata_table

A data frame whose columns consist of sample identifiers (sample_ID), individual, time point and other meta data. Each row corresponds to one sample_ID. Metadata table should have the same number of rows as feature table does. Please avoid using characters that don't belong to ASCII printable characters for the column names.

feature_table

A data frame whose columns only consist of sample identifiers (sample_ID) and features (dependent variables, e.g. microbiome). Each row corresponds to one sample_ID. Please do not include any columns other than sample_ID and features. Please avoid using characters that don't belong to ASCII printable characters for the column names. Also, feature table should have the same number of rows as metadata table does.

sample_ID

The name of the column which stores sample identifiers. Please make sure that sample_IDs are unique for each sample, and that metadata and feature tables have the same sample_IDs. If sample_IDs don't match between the two tables, it will fail to join them together. This should be a string, e.g. "Sample_ID"

individual

The name of the column which stores individual information in the metadata table. This should be a string, e.g. "Individual"

keep_id

A boolean vector indicating whether keep sample_ID column in the output master table. The default is FALSE.

Details

This function joins metadata and feature tables by the sample_ID column. Users can create master tables compatible with the format of longdat_disc() and longdat_cont() input easily.This function outputs a master table with individual as the first column, followed by time point and other metadata, and then by feature columns.

Value

a data frame which complies with the required format of an input data frame for longdat_disc() and longdat_cont().

Examples

test_master <- make_master_table(
metadata_table = LongDat_disc_metadata_table,
feature_table = LongDat_disc_feature_table,
sample_ID = "Sample_ID",
individual = "Individual")
