| Title: | Create View Tabs of Pipe Chains |
| Version: | 0.1.0 |

| Description: | Debugging pipe chains often consists of viewing the output after each step. This package adds RStudio addins and two functions that allow outputing each or select steps in a convenient way. |

%P>% Prints and pipes
Description
This pipe variant prints the object received from the left hand side prior to piping it to the right hand side.
Usage
lhs %P>% rhs
Arguments
lhs |
The left hand side of the pipe. |
rhs |
The right hand side of the pipe. |
Value
called for side effects
Note
This code is experimental. Use at your own risk.
Examples
if (!require(dplyr)) stop("Examples need dplyr to run")
mtcars %>%
filter(am == 1) %P>%
select(qsec)
Prints each pipe step in current text selection
Description
Reads the currently selected text from the RStudio API and prints for each pipe step the resulting object if unique. Data frames are converted by as_tibble(). Meant to be called as an RStudio addin.

Usage
printPipeChain()
printPipeChain()
Value
No return value, called for side effects
Prints the return objects of all pipe steps to console
Description
Added as last command to a pipe, prints for each pipe step the resulting object to the console if unique. Data frames are converted by as_tibble().
Usage
print_pipe_steps(.data, cmd = print_command, all = FALSE)
Arguments
.data |
The data, normally handed over from the prior pipe step. |
cmd |
The command to be evaluated for each object. Takes ps object of step example. |
all |
Whether you want to print objects even if they are identical. Helpful when you want to display changes in grouping. |
Value
The unchanged data
Examples
if (!require(dplyr)) stop("Examples need dplyr to run")
mtcars %>%
filter(am == 1) %>%
select(qsec) %>%
print_pipe_steps() -> result
my_print_cmd <- c(
"message(title);",
"skimr::skim_tee(data = ps%d)"
)
mtcars %>%
select(am, hp, mpg) %>%
group_by(am) %>%
print_pipe_steps(my_print_cmd, all = TRUE) %>%
summarize(
nobs = n(),
mean_hp = mean(hp),
mean_mpg = mean(mpg)
)
Creates a View() output for each pipe step in current text selection
Description
Reads the currently selected text from the RStudio API and displays a data view in the source pane for each pipe step creating a unique object. Meant to be called as an RStudio addin.
