cpSta {ctrlGene} | R Documentation |
This function calculates descriptive statistics of genes.
cpSta(expression, ctVal = TRUE)
expression |
a matrix of expression levels. Each row corresponds to a sample and each column to a gene. |
ctVal |
a logical value indicating data type. If ct-values are input, ctVal=TRUE, otherwise, ctVal=FALSE. |
A matrix of descriptive statistics:
N: number of samples;
GM[CP]: the geometric mean of CP;
AM[CP]: the arithmetic mean of CP;
Min[CP] and Max [CP]: the extreme values of CP;
SD[+/- CP]: the standard deviation of the CP;
CV[CP]: the coefficient of variance expressed as a percentage on the CP level;
Min[x-fold] and Max [x-fold]: the extreme values of expression levels expressed as an absolute x-fold over- or under-regulation coefficient;
SD[+/- x-fold]: standard deviation of the absolute regulation coefficients.
