Bind data to a lens

To flatten lens composition, you can prespecify the data the lens with be applied to by constructing an objectoscope. These can be integrated easily with normal data pipelines.

oscope(d, l = id_l)

Arguments

d	The data for interest
l	The lens to bind the data to. Defaults to the identity lens

Examples

list(a = 5, b = 1:3, c = 8) %>%
  oscope()   %.%
  index_l("b") %.%
  index_l(1)   %>%
  set(10)
#> $a
#> [1] 5
#> 
#> $b
#> [1] 10  2  3
#> 
#> $c
#> [1] 8
