I have done a Heat Map using the function heatmap.2 of gplots in R, but I don't have an idea of how to coloring the branches and tick labels per groups (Eg. if I cut the tree to have four gruops like in my second figure). I have checked that it is possible to color the dendrogram alone using dendextend package.
Also there is a heatmap here: selecting number of leaf nodes of dendrogram in heatmap.2 in R with a colored dendrogram, but I can't implement it in my example.
Somebody can help me with this issue?
Update
This is my Heat Map:
and I would like to have one like this with branches and tick labels in color according their four groups (this figure was edited with Illustrator to explain this question):
Here is the data and code that I have used:

Solution: use the color_branches function from the dendextend package (or the set function, with the "branches_k_color", "k", and "value" parameters ).
First we need to get the data into R and create the relevant objects ready (this part is the same as the code in the question):
test <- read.delim("clipboard", sep="")
rnames <- test[,1]
test <- data.matrix(test[,2:ncol(test)]) # to matrix
rownames(test) <- rnames
test <- scale(test, center=T, scale=T) # data standarization
test <- t(test) # transpose
## Creating a color palette & color breaks
my_palette <- colorRampPalette(c("forestgreen", "yellow", "red"))(n = 299)
col_breaks = c(seq(-1,-0.5,length=100), # forestgreen
seq(-0.5,0.5,length=100), # yellow
seq(0.5,1,length=100)) # red
# distance & hierarchical clustering
distance= dist(test, method ="euclidean")
hcluster = hclust(distance, method ="ward.D")
Next, we get the dendrogram and the heatmap ready:
dend1 <- as.dendrogram(hcluster)
# Get the dendextend package
if(!require(dendextend)) install.packages("dendextend")
library(dendextend)
# get some colors
cols_branches <- c("darkred", "forestgreen", "orange", "blue")
# Set the colors of 4 branches
dend1 <- color_branches(dend1, k = 4, col = cols_branches)
# or with:
# dend1 <- set(dend1, "branches_k_color", k = 4, value = cols_branches)
# get the colors of the tips of the dendrogram:
# col_labels <- cols_branches[cutree(dend1, k = 4)] # this may need tweaking in various cases - the following is a more general solution.
# The following code will work on its own once I uplode dendextend 0.18.6 to CRAN - but that can
# take several good weeks until that happens. In the meantime
# Either use devtools::install_github('talgalili/dendextend')
# Or just the following:
source("https://raw.githubusercontent.com/talgalili/dendextend/master/R/attr_access.R")
col_labels <- get_leaves_branches_col(dend1)
# But due to the way heatmap.2 works - we need to fix it to be in the
# order of the data!
col_labels <- col_labels[order(order.dendrogram(dend1))]
# Creating Heat Map
if(!require(gplots)) install.packages("gplots")
library(gplots)
heatmap.2(test,
main = paste( "test"),
trace="none",
margins =c(5,7),
col=my_palette,
breaks=col_breaks,
dendrogram="row",
Rowv = dend1,
Colv = "NA",
key.xlab = "Concentration (index)",
cexRow =0.6,
cexCol = 0.8,
na.rm = TRUE,
RowSideColors = col_labels, # to add nice colored strips
colRow = col_labels # to add nice colored labels - only for qplots 2.17.0 and higher
)
Which produces this plot:
For more details on the package, you can have a look at its vignette.
p.s.: to get the labels colored depends on parameters of heatmap.2, and this should be asked from the maintainer of gplots (i.e.: from greg at warnes.net)
update: this answer now includes the new "colRow" parameter in qplots 2.17.0.
