Import Data

wine <- read_csv("data/wine_quality.csv")

Quick overview of the type of wine in data set.

ggplot(data = wine, aes(x= type)) + geom_bar() + labs(
  title = "Breakdown of Wine by Type", 
  x = "Type of Wine", 
  y = "Frequency of Wine"
)

Only interested in white wine, hence filter to white wine.

  1. Drop column 12: Quality of Wine to make the data more clean for clustering
  2. Drop column 13 on type as already filtered down to white wine, all will be “white:
whitewine <- wine %>% 
  filter(type == "white") %>%
  select(c(1:11))

Scatter Plot Matrix (Interactive)

Plotting the scatter plot matrix.

  • As the plot is a widget itself, the width and height of the display is defined within the variable (500 pixel width and 500 pixel height).

  • distribType = 1: Density Plot, 2 = Histogram

  • corrPlotCS = Setting color for the scheme. (e.g “YlOrRd”)

# returning density plot
scatterPlotMatrix(whitewine, corrPlotType = "Text", 
                  distribType = 1, 
                  width = 500, 
                  height = 500)
# returning histogram
scatterPlotMatrix(whitewine, corrPlotType = "Text", 
                  distribType = 2, 
                  width = 500, 
                  height = 500)

Exposing control for the widget with controlWidgets = TRUE

scatterPlotMatrix(whitewine, corrPlotType = "Text", 
                  distribType = 2, 
                  width = 500, 
                  height = 500, 
                  controlWidgets = TRUE)

Clustering

Determining optimal number of clusters

#set.seed(1234)
#gap_stat <- clusGap

#fviz_gap_stat(gap_stat)

Deriving the 4 clusters

  • set.seed defined to ensure that it starts from the same position to return similar clusters per iteration
set.seed(123)
kmeans4 <- kmeans(whitewine, 4, nstart = 25)
print(kmeans4)
K-means clustering with 4 clusters of sizes 757, 978, 1444, 1719

Visualisation technique to show the cluster group.

fviz_cluster(kmeans4, data = whitewine)

Take results from kmeans and pull out the cluster field and append back to the white wine data set.

whitewine <- whitewine %>% mutate(Cluster = kmeans4$cluster)

Factorize the cluster column (1,2,3,4,5), as the values returned from cluster is as integer (continuous), should convert into discrete categories.

whitewine$Cluster <- as_factor(whitewine$Cluster)

Plotting the parallel plot

  1. Rotate labels for axis to minimise overlap.
