Examples

## DataFrame ====
binary <- seq(from = 0L, to = 1L)
df <- DataFrame(
    a = rep(x = binary, times = 50L),
    b = rep(x = binary, each = 50L)
)
lapply(df, class)

#> $a
#> [1] "integer"
#> 
#> $b
#> [1] "integer"
#> 
x <- encode(df)
lapply(x, class)

#> $a
#> [1] "Rle"
#> attr(,"package")
#> [1] "S4Vectors"
#> 
#> $b
#> [1] "Rle"
#> attr(,"package")
