createClusterPairsPlot: Create cluster variable plot.

In toaster: Big Data in-Database Analytics that Scales with Teradata Aster Distributed Platform

Description

Create cluster variable plot.

Usage

createClusterPairsPlot(km, include = NULL, except = NULL, baseSize = 12,
  baseFamily = "serif", title = "Cluster Variable Pairs", ticks = FALSE,
  defaultTheme = theme_tufte(base_size = baseSize, base_family = baseFamily,
  ticks = ticks), themeExtra = theme(), ...)

Arguments

km	an object of class "toakmeans" returned by computeKmeans.
include	a vector of column names to include. Plot never contains variables other than in the list. Plot would never include idAlias even if it is included explicitly.
except	a vector of column names to exclude. Plot never contains variables from the list.
baseSize	theme base font size.
baseFamily	theme base font family.
title	plot title.
ticks	logical Show axis ticks using default theme settings (see defaultTheme)?
defaultTheme	plot theme settings with default value theme_tufte. More themes are available here: ggtheme (by ggplot2) and ggthemes.
themeExtra	any additional theme settings that override default theme.
...	other parameters being suplied to geom's aes.

Value

ggplot object

Examples

if(interactive()){
# initialize connection to Lahman baseball database in Aster 
conn = odbcDriverConnect(connection="driver={Aster ODBC Driver};
                         server=<dbhost>;port=2406;database=<dbname>;uid=<user>;pwd=<pw>")
                         
km = computeKmeans(conn, "batting", centers=5, iterMax = 25,
                   aggregates = c("COUNT(*) cnt", "AVG(g) avg_g", "AVG(r) avg_r", "AVG(h) avg_h"),
                   id="playerid || '-' || stint || '-' || teamid || '-' || yearid", 
                   include=c('g','r','h'), scaledTableName='kmeans_test_scaled', 
                   centroidTableName='kmeans_test_centroids',
                   where="yearid > 2000")
km = computeClusterSample(conn, km, 0.01)
createClusterPairsPlot(km, title="Batters Clustered by G, H, R", ticks=FALSE)
}
