Arguments

sMap

an object of class "sMap" or a codebook matrix

data

a data frame or matrix of input data

sBase

an object of class "sBase"

base.color

short name for the colormap used to encode bases (in row side bar). It can be one of "jet" (jet colormap), "bwr" (blue-white-red colormap), "gbr" (green-black-red colormap), "wyr" (white-yellow-red colormap), "br" (black-red colormap), "yr" (yellow-red colormap), "wb" (white-black colormap), and "rainbow" (rainbow colormap, that is, red-yellow-green-cyan-blue-magenta). Alternatively, any hyphen-separated HTML color names, e.g. "blue-black-yellow", "royalblue-white-sandybrown", "darkgreen-white-darkviolet". A list of standard color names can be found in http://html-color-codes.info/color-names

base.separated.arg

a list of main parameters used for styling bar separated lines. See 'Note' below for details on the parameters

base.legend.location

location of legend to describe bases. If "none", this legend will not be displayed

reorderRow

the way to reorder the rows within a base. It can be "none" for rows within a base being reorded by the hexagon indexes, "hclust" for rows within a base being reorded according to hierarchical clustering of patterns seen, "svd" for rows within a base being reorded according to svd of patterns seen

keep.data

logical to indicate whether or not to also write out the input data. By default, it sets to false for not keeping it. It is highly expensive to keep the large data sets

...

additional graphic parameters used in "visHeatmapAdv". For most parameters, please refer to https://www.rdocumentation.org/packages/gplots/topics/heatmap.2

Value

a data frame with following components:

Note: the returned data has rows in the same order as visualised in the heatmap

# 1) generate an iid normal random matrix of 100x10 
data <- matrix( rnorm(100*10,mean=0,sd=1), nrow=100, ncol=10)

## Not run: 
# 2) get trained using by default setup
sMap <- sPipeline(data=data)

# 3) partition the grid map into clusters using region-growing algorithm
sBase <- sDmatCluster(sMap=sMap, which_neigh=1,
distMeasure="median", clusterLinkage="average")

# 4) heatmap visualisation
output <- visDmatHeatmap(sMap, data, sBase,
base.legend.location="bottomleft", labRow=NA)

## End(Not run)
