See if this gives you the presentation you want: x <- read.table(textConnection("Name Class a Class1 a Class4 b Class2 b Class1 d Class3 d Class5 e Class4 e Class2"), header = TRUE) closeAllConnections() # add columns of numeric values of factors x$name <- as.integer(x$Name) x$class <- as.integer(x$Class) # create plot area plot(0 , type = 'n' , xaxt = 'n' , yaxt = 'n' , xlab = '' , ylab = '' , xlim = c(0, max(x$class)) , ylim = c(0, max(x$name)) ) # now plot the rectangles rect( xleft = x$class - 1 , ybottom = x$name - 1 , xright = x$class , ytop = x$name , col = x$name ) # add the labels axis(1 , at = seq(0.5, by = 1, length = length(levels(x$Class))) , labels = levels(x$Class) ) axis(2 , at = seq(0.5, by = 1, length = length(levels(x$Name))) , labels = levels(x$Name) )
