R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

df_customer <- read.csv(“df_customer.csv”) head(df_customer)

length(unique(df_customer$ID_Pelanggan))

sort(table(df_customer$ID_Pelanggan), decreasing = TRUE)[1:3]

aggregate(Penghasilan ~ Jenis_Kelamin, data = df_customer, mean)

aggregate(Total_Belanja ~ Jenis_Kelamin, data = df_customer, mean)

aggregate(Penghasilan ~ Tempat_Tinggal, data = df_customer, mean)

aggregate(Total_Belanja ~ Tempat_Tinggal, data = df_customer, mean)

df_customer[order(-df_customer$Total_Belanja), c(“ID_Pelanggan”, “Total_Belanja”)] |> head(5)

table(df_customer$Jenis_Kelamin)

df_customer\(Kategori_Penghasilan <- cut(df_customer\)Penghasilan, breaks = c(-Inf, 5000000, 10000000, Inf), labels = c(“Rendah”, “Menengah”, “Tinggi”)) table(df_customer$Kategori_Penghasilan)

df_customer[df_customer$Total_Belanja > 5000000, c(“ID_Pelanggan”, “Total_Belanja”)]

unique(df_customer$ID_Pelanggan)
