The reason I need geocoding at last blog is that I want to map the sale data in Tableau. Before I tried to use python script and google geocoding API key, I adopted the geocode() function from the ggmap library in R and put them in tableau calculation function. While, It doesn't work.
Luckily, the other R package works! I use 'mvoutliers' package to analyze the outlier in the Tableau graph. R gives Tableau more analysis tools. It is amazing to use them together !
IF SCRIPT_REAL("
library(mvoutlier);
sign2(cbind(.arg1))$wfinal01
",
SUM([Sale Price])
