| EachGeneDataDistView {BNArray} | R Documentation |
Plot a histgram of the expression levels of one or more genes distribution at a time across total experiments.
EachGeneDataDistView(begin, end, expr.matrix)
begin |
the beginning gene number to plot |
end |
the ending gene number to plot |
expr.matrix |
a microarray expression matrix object with rows containing a gene expression levels across multi-experiment while columns denoting expression levels of all genes contained in one microarray slide. |
View a gene expression level distribution within a total microarray experiment data set. Normally,
we could perform further statistical test and find it is a normal distribution with u=mean(vec),S=var(vec),
vec is the expression vector of a specified gene.
No value returned.
