A block of code is set as follows:

install.packages('rpart',repos='http://cran.us.r-project.org')
library(rpart)
cars <- read.table("C:\\!Slaven\\6 KNJIGA\\4 Advanced analytics\\4 decision tree\\new_or_used_car.csv", header=T, sep=",")
fit <- rpart(FuturePurchase ~ Age + Gender + Education + FamilyStatus + CurrentCar + AgeOfCurrentCar + MunicipalityType, method="class", data=cars)
plot(fit, uniform=TRUE, main="Classification of new cars buyers")
text(fit, all=TRUE, cex=.8)

Any command-line input or output is written as follows:

set enable_result_cache_for_session to off;

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "From the Connect pane on the left-hand side, choose the Text file option."
