[r] How to filter a data frame

I have a data frame and tried to select only the observations I'm interested in by this:

data[data["Var1"]>10]

Unfortunately, this command destroys the data.frame structure and returns a long vector.

What I want to get is the data.frame shortened by the observations that don't match my criteria.

Another method utilizing the dplyr package:

library(dplyr)
df <- mtcars %>%
        filter(mpg > 25)

Without the chain (%>%) operator:

library(dplyr)
df <- filter(mtcars, mpg > 25)
