| EachMicroarrayDataDistView {BNArray} | R Documentation |
Plot a histgram of the expression levels of one or more microarray data distribution at a time containing all gene in the microarray slides.
EachMicroarrayDataDistView(begin, end, expr.matrix, n.changed)
begin |
the beginning microarray number to plot |
end |
the ending microarray 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. |
n.changed |
the number of genes that differentially express |
View a microarray expression level distribution containing all the genes in the slide. 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 microarray.
No value returned.
