heatmap.plus.package {heatmap.plus} | R Documentation |
Call exactly as you would the base heatmap() function. Only two optional parameters' values should differ, RowSideColors and ColSideColors. They should be matrices instead of vectors, where colnames() on each matrix is a vector of the annotation track names. One annotation track will be drawn per column. See help('heatmap') for documentation of arguments not documented here.
heatmap.plus(x, Rowv = NULL, Colv = if (symm) "Rowv" else NULL, distfun = dist, hclustfun = hclust, reorderfun = function(d, w) reorder(d, w), add.expr, symm = FALSE, revC = identical(Colv, "Rowv"), scale = c("row", "column", "none"), na.rm = TRUE, margins = c(5, 5), ColSideColors, RowSideColors, cexRow = 0.2 + 1/log10(nr), cexCol = 0.2 + 1/log10(nc), labRow = NULL, labCol = NULL, main = NULL, xlab = NULL, ylab = NULL, keep.dendro = FALSE, verbose = getOption("verbose"), ...)
x |
numeric matrix of the values to be plotted. |
Rowv |
determines if and how the row dendrogram should be
computed and reordered. Either a dendrogram or a
vector of values used to reorder the row dendrogram or
NA to suppress any row dendrogram (and reordering) or
by default, NULL , see Details below. |
Colv |
determines if and how the column dendrogram should be
reordered. Has the same options as the Rowv argument above and
additionally when x is a square matrix, Colv =
"Rowv" means that columns should be treated identically to the rows. |
distfun |
function used to compute the distance (dissimilarity)
between both rows and columns. Defaults to dist . |
hclustfun |
function used to compute the hierarchical clustering
when Rowv or Colv are not dendrograms. Defaults to
hclust . |
reorderfun |
function(d,w) of dendrogram and weights for
reordering the row and column dendrograms. The default uses
reorder.dendrogram . |
add.expr |
expression that will be evaluated after the call to
image . Can be used to add components to the plot. |
symm |
logical indicating if x should be treated
symmetrically; can only be true when x is a square matrix. |
revC |
logical indicating if the column order should be
rev ersed for plotting, such that e.g., for the
symmetric case, the symmetry axis is as usual. |
scale |
character indicating if the values should be centered and
scaled in either the row direction or the column direction, or
none. The default is "row" if symm false, and
"none" otherwise. |
na.rm |
logical indicating whether NA 's should be removed. |
margins |
numeric vector of length 2 containing the margins
(see par(mar= *) ) for column and row names, respectively. |
ColSideColors |
(optional) character matrix with number of rows matching number of rows in x. Each column is plotted as a row similar to heatmap()'s ColSideColors. colnames() will be used for labels if present. |
RowSideColors |
(optional)character matrix with number of rows matching number of columns in x. Each column is plotted as a row similar to heatmap()'s RowSideColors. colnames() will be used for labels if present. |
cexRow, cexCol |
positive numbers, used as cex.axis in
for the row or column axis labeling. The defaults currently only
use number of rows or columns, respectively. |
labRow, labCol |
character vectors with row and column labels to
use; these default to rownames(x) or colnames(x) ,
respectively. |
main, xlab, ylab |
main, x- and y-axis titles; defaults to none. |
keep.dendro |
logical indicating if the dendrogram(s) should be
kept as part of the result (when Rowv and/or Colv are
not NA). |
verbose |
logical indicating if information should be printed. |
... |
additional arguments passed on to image ,
e.g., col specifying the colors. |
