pipefittr

To take nested function calls and convert them to a more readable form using magrittr’s pipes.

Examples:

e.g. (example taken from Hadley Wickham)

calling the add-in on:

foo_foo <- little_bunny()
bop_on( scoop_up( hop_through(foo_foo, forest), field_mouse ), head )

will return:

foo_foo <- little_bunny()
foo_foo %>% 
  hop_through(forest) %>% 
  scoop_up(field_mouse) 
  %>% bop_on(head)

installation

# install a dev version using
devtools::install_github("houstonusers/pipefittr")

This should automatically install a Rstudio add-in as well.

to do

another example which does not work currently

ostensibly, the (same?) function would also be able to remedy horrendous situations like this:

tmp_bunny1 <- foo_foo
tmp_bunny2 <- hop_through(tmp_bunny1, forest)
tmp_bunny3 <- scoop_up(tmp_bunny2, field_mouse)
tmp_bunny4 <- bop_on(tmp_bunny3, head)

this would resolve to:

foo_foo <- little_bunny()
tmp_bunny4 <- foo_foo %>% 
  hop_through(forest) %>% 
  scoop_up(field_mouse) 
  %>% bop_on(head)

same as above with the minor difference that it would now be assigned to tmp_bunny4. It can be up to the user to change that later.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
