URG_getFactor {Corbi} | R Documentation |
Calculate the normalization factor for each sample by using URG (uniform ratio graph) method.
URG_getFactor(expr.matrix, p.edge = 0.25, p.gene = 0.4, log.expr = FALSE)
expr.matrix |
The expression matrix. Each row represents a gene and each column represents a sample. |
p.edge |
The percentage of gene pairs that are selected into the uniform ratio graph. |
p.gene |
The maximal percentage of genes that are selected as the stable genes. |
log.expr |
Logical variable indicating whether the input expression matrix is in logarithmic scale. |
This function will return a numeric vector with each element [i] represents the normalization factor of sample (i).
