featuredata |
featuredata A data frame in the featuredata format. This is a dataframe with metabolites in columns and samples in rows. Unique sample names should be provided as row names. See NormalizeMets Vignette for details. |
base |
The base with respect to which logarithms are computed. The default computes the natural logarithm. |
saveoutput |
A logical indicating whether the output should be saved as a .csv file. |
outputname |
The name of the output file if the output has to be saved. |
zerotona |
A logical indicating whether any zeros should be converted to missing prior to log transforming. By default, this is set to FALSE. |
The result is an object of class
alldata
.
