Load the data
The data can be prepared in csv or text file to load the data in to R
Type: read.csv("your file name.csv")
e.g data <- read.csv (“list.csv”)
To name the rows of the heat map
Type: Row.names(data) <- data$Name
To exclude the first column from the heat map
Type:Data <- data [,2: n]
where n is the number of columns to be included in the heat map
To change the loaded data in to data matrix
Type: Data_matrix <- data.matrix (data)
To use gnuplot library
Note: Gnuplot package must be installed in R.
Type:library("gplots")
To make heat map
Type: heatmap.2 (Data_matrix, dendrogram="row", col= redgreen (75), scale="none", key = TRUE, keysize = 1.0, margins = c(4,30), density.info="none", trace="none")
