For example, If we want to compare the sales between different product categories, product color, we can use this R … By default, the categorical axis line is suppressed. To better understand the role of group, we need to know individual geoms and collective geoms.Geom stands for geometric object. I will be showing two ways which you can do this. showCols(bg="gray20", cl=colors()[1:60], rot=30, cex=0.9) barplot(c(2, 5), col=c("chartreuse", "blue4")) To view all the built-in color names which R knows about (n = 657), use the following R code : showCols(cl= colors(), bg="gray33", rot=30, cex=0.75) A polygon consists of multiple rows of data so it is a collective geom.
