create_Metabolite | R Documentation |
Create a Metabolite object from three input data sets: 1) metabolite measurements (eg. peak area data or normalized data), and 2) metabolite annotation (eg. chemical annotation) 3) sample annotation (eg. sample meta data)
create_Metabolite(
assayData,
featureData,
sampleData,
featureID = "featureID",
sampleID = "sampleID",
logs = "",
miscData = list()
)
assayData |
a data.frame or data.table of metabolite measurements (peak area data or normalized data, sample [row] * feature [column]). |
featureData |
a data.frame or data.table of metabolite annotation (chemical annotation) |
sampleData |
a data.frame or data.table of sample annotation (sample meta data). |
featureID |
a character of the metabolite ID column (in feature file and the column names of data), default: CHEM_ID (provided from Metabolon file). |
sampleID |
a character of the sample ID column (in sample and the first column of data), default: PARENT_SAMPLE_NAME (provided from Metabolon file). |
logs |
Log information. |
miscData |
Ancillary data. |
A Metabolite object with slots: assayData, featureData, and sampleData.
