Ggplot2 and K-means Method in R
install.packages("ggplot2")library(ggplot2)# load the datesetdata(mtcars)
after drawing the elbow curve, you can guess, 2 or 3 different numbers of clusters, depending on how the elbow bends ( the sharper the elbow bends, meaning the error drops very sharpy, then pick 1 k, if the error drops NOT so sharply, then pick 2, 3, or 4 different k value.
Sharpy e.g 90 degree bend not so sharply e.g 45 - 60 degree
you MUST summarize your results, e.g. your choice(s) of number of clusters, relationship between wt and mpg etc.
any relationship between mpg and wt?
