barrow function

Barplot per row with respect to a set of quantitative variables

Returns as many barplots as there are rows in a matrix. The barplots are automatically generated for all the quantitative variables.

barrow(donnee, numr = 2, numc = 2, numchar = 8, color = "lightblue",
      title = NULL)

Arguments

• donnee: a data frame of dimension (p,q), where p is the number of products and q is the number of sensory descriptors for instance
• numr: the number of barplots to be displayed per row (by default 2)
• numc: the number of barplots to be displayed per column (by default 2)
• numchar: the number of character used to write the boxplot labels (by default 8)
• color: the color of the barplots (by default "lightblue")
• title: the title used in the graphs
