veteran (cancer) Veterans' Administration Lung Cancer studyFör att se vilka datamängder som finns i ett specifikt paket används följande kommando:
R
data(package="survival")Alla dessa datamängder är avsedda att användas som övningsdata, exempelvis för att experimentera med funktioner och förstå hur de fungerar. Om du vill använda någon av dessa datamängder skriver du namnet på den i funktionen data(). För att ladda datamängderna AirPassengers och lakers skriver man som följer:
R
data("AirPassengers")
data("lakers")Detta laddar datamängderna, vilka förblir inaktiva tills de faktiskt används. Detta kommer märkas i din Environment, genom att objektet flaggas med <Promise>, som framgår av Figur 10.1.
När du använder datamängden kommer den aktiveras och <Promise> försvinner.
I paketet survival finns flera användbara datamängder för överlevnadsanalys. För att ladda alla dataset med cancerpatienter skriver man kommandot:
R
# Aktivera paketet survival
library(survival)
# Ladda alla dataset med cancerstudier
data(cancer)Då aktiveras samtliga datamängder med cancerstudier, vilket framgår i vår Environment:
