40 plotOrdplotOrdPlot of either PCA or MDS coordinates for the distances of normalizedor unnormalized counts.DescriptionUsageThis function plots the PCA / MDS coordinates for the "n" features of interest. Potentially uncoveringbatch effects or feature relationships.plotOrd(obj, tran = TRUE, comp = 1:2, log = TRUE, norm = TRUE,usePCA = TRUE, useDist = FALSE, distfun = stats::dist,dist.method = "euclidian", ret = FALSE, n = NULL, ...)ArgumentsobjtrancompusePCAuseDistdistfundist.methodlognormretnValueA MRexperiment object or count matrix.Transpose the matrix.Which components to displayTRUE/FALSE whether to use PCA or MDS coordinates (TRUE is PCA).TRUE/FALSE whether to calculate distances.Distance function, default is stats::distIf useDist==TRUE, what method to calculate distances.Whether or not to log2 the counts - if MRexperiment object.Whether or not to normalize the counts - if MRexperiment object.Whether or not to output the coordinates.Number of features to make use of in calculating your distances....
