    mediana = median(price,na.rm = TRUE),
    minimum = min(price),
    maksimum = max(price),
    liczba = n()
  )
## # A tibble: 3 × 6

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
