xlab: This parameter is the label for x axis in bar chart. If you want to create a clustered barplot, with different bars for different groups of data, you can enter a matrix as the argument to height.R will then plot each column of the matrix as a separate set of bars. Syntax. If it is a matrix with option false corresponds to sub bars, and true denotes to create a horizontal bar. If height is a vector, the plot consists of a sequence of rectangular bars with heights given by the values in the vector. This can be done by using barplot function but we need to convert the data frame to matrix and take the transpose of it. Matrix can be created using the matrix() function.Dimension of the matrix can be defined by passing appropriate value for arguments nrow and ncol.Providing value for both dimension is not necessary.
