Correlation networks are increasingly being used in bioinformatics applications. For example, weighted gene co-expression network analysis is a systems biology method for describing the correlation patterns among genes across microarray samples. Weighted correlation network analysis (WGCNA) can be ...

Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components. The number of principal components is less tha ...
I am working on human colon cancer recently. I want to see different expression gene in colon cancer cells lines. I downloaded GSE46549 dataset from NCBI (gene expression analysis of 6 colon cancer cell lines (HCT116, HT-29, RKO, SW480, LIM1512 and CaCo2), http://www.ncbi.nlm.nih.gov/ge ...
First, we need initiate a new plot with plot function without x-y axis. If you want to define xlim and/or ylim, do this in this initiated plot with parameters xlim and ylim. plot (-2:4, c(-5, -4, 3, 4, 5, 2, 3), axes=FALSE, xlim=c(-6,6), ylim=c(-6, 6), xlab="", ylab="", main ...
