# Installation

You can install the released version of ViewPipeSteps from CRAN with:

```r
install.packages("ViewPipeSteps")

Or install the development version from GitHub with:

remotes::install_github("daranzolin/ViewPipeSteps")

Overview

ViewPipeSteps helps to debug pipe chains in a slightly more elegant fashion. Print/View debugging isn't sexy, but instead of manually inserting %>% View() after each step, spice it up a bit by, e.g., highlighting the entire chain and calling the viewPipeChain addin:

Thanks to @batpigandme for the the gif!

Alternatively, you can:

• Print each pipe step of the selction to the console by using the printPipeChain addin.
• Print all pipe steps to the console by adding a print_pipe_steps() call to your pipe.

diamonds %>%
  select(carat, cut, color, clarity, price) %>%
  group_by(color) %>%
  summarise(n = n(), price = mean(price)) %>%
  arrange(desc(color)) %>%
  print_pipe_steps() -> result

• Try your luck with the experimental %P>% pipe variant that prints the output of the pipe's left hand side prior to piping it to the right hand side.

diamonds %>%
  select(carat, cut, color, clarity, price) %>%
  group_by(color) %>%
  summarise(n = n(), price = mean(price)) %P>%
  arrange(desc(color)) -> result

Installation

devtools::install_github("daranzolin/ViewPipeSteps")

More Examples

Check tools/test_cases.R for more elaborate examples.

Future Work

• Verify that %P>% is implemented in a useful way and does it what it is supposed to do.
