Raw
df-subset-filter
# Testdaten
df <- data.frame(category = c(1,2,3,1,3,2,1), value = rep(10, 7))
# Variante 1:
# Die Klassiker
df[df$category == 2,]
subset(df, category == 2)
# Variante 2:
# mit dem dplyr package. Unterschied: die Zeilen bekommen neue fortlaufende Nummern
# das kann Vorteile bieten..
filter(df, category == 2)
