diverse classes


Recurring Problems

In R there are usually lots of different ways

to solve a problem

We did this already this way, whyare we doing it another way?


Recurring Problems

Steep learning curve

What does this Error Message mean? I‘m having problems

solving this exercise.

This is in SPSS much easier

I will neverunder-stand R


Recurring Problems

Technical hurdles

I´m missing the permissionto install packages

I have to use externalsoftware

Writing code in front

cars <- read.csv(file = "Data/carsMO.csv", stringsAsFactors = FALSE)

select(cars, Manufacturer, Modell, contains("sales", ignore.case = TRUE))select(cars, Manufacturer, Modell, Sales:Sales_grouped)

mutate(cars, weight_to_hp = HP/Weight) %>%filter(weight_to_hp > mean(weight_to_hp, na.rm = TRUE)) %>%arrange(desc(weight_to_hp))%>%select(Modell, weight_to_hp)

abs_loss_data <- cars %>%mutate(absolute_loss = Purchase_price - Resaleprice) %>%arrange(desc(absolute_loss)) %>%select(Modell, contains("price"), absolute_loss) %>%filter(!is.na(absolute_loss))

Usual Course

Excercises

Don‘t make itto difficult

Now that you know, what a list isplease load this dataset, apply a cluster analysis on it and create

an appealing report
