Title: | Gene Scoring from Count Tables |
---|---|
Description: | Provides two methods for automatic calculation of gene scores from gene count tables: the z-score method, which requires a table of samples being scored and a count table with control samples, and the geometric mean method, which does not rely on control samples. The mathematical methods implemented are described by Kim et al. (2018) <doi:10.1089/jir.2017.0127>. |

This function computes the geometric mean for each sample in the given count table.
geomean(count_table)
geomean(count_table)
count_table |
A data frame of gene count data (genes as rows, samples as columns). All columns must be numeric. |
A data frame with the geometric means per sample and the sample IDs.

This function computes a Z-score sum for each sample in the given "scored" count table, based on the means and SDs of the genes in the control table.
zscore(scored_table, control_table)
zscore(scored_table, control_table)
scored_table |
Data frame of samples to be scored (genes as rows, samples as columns). All columns must be numeric. |
control_table |
Data frame of control samples (genes as rows, samples as columns). All columns must be numeric. |
A data frame with the sum of Z-scores per sample and the sample IDs.
