Description

Create a matahari-esque data frame from a file.

Usage

dance_recital(code, evaluate = TRUE)

Arguments

code

A string or the path to a file containing R code.

evaluate

Logical, indicating whether to evaluate the code, default is TRUE

Examples

library(knitr)

# Evaluate a string of R code
kable(dance_recital("x <- 4; x *7"))

## |expr   |value |error |output |warnings     |messages     |
## |:------|:-----|:-----|:------|:------------|:------------|
## |x <- 4 |4     |NULL  |       |character(0) |character(0) |
## |x * 7  |28    |NULL  |       |character(0) |character(0) |

# Evaluate an R script. We have provided an R script for testing purposes.

# Access log of your session
kable(dance_tbl()[3:4, 1:5])

## |expr   |value  |path |contents |selection |
## |:------|:------|:----|:--------|:---------|
## |Hello! |Hello! |NA   |NA       |NA        |
## |4 + 4  |8      |NA   |NA       |NA        |

# Deletes the lgo of your session
dance_remove()

# With no log, dance_tbl() returns NULL invisibly.
withVisible(dance_tbl())

## $value

Start Spying

Description

Start logging your R console activity. If you're using RStudio the contents of your current editor tab will also be tracked. All logging takes place when R code is executed in the R console.

Usage

dance_start(
  expr = TRUE,
  value = FALSE,
  path = FALSE,
  contents = FALSE,
  selection = FALSE
)

Arguments

expr

The R expressions typed into the R console will be logged unless this is set to FALSE.

value

Values that are computed on the R console will be logged unless this is set to FALSE.

path

The path to the file in focus on the RStudio editor will be logged unless this is set to FALSE.

contents

The file contents of the RStudio editor tab in focus will be logged unless this is set to FALSE.

selection

The text that is highlighted in the RStudio editor tab in focus will be logged unless this is set to FALSE.

Examples

## Not run: 
# Begin recording your R session.
dance_start()

# Each of the following expressions adds a row to the tibble that tracks
# the execution of your R code.
"Hello!"
4 + 4
x <- 7
x^2
rm(x)
x

# This stops recording your R session.
dance_stop()

## End(Not run)

Stop Spying

Description

Pause the current logging session.

Usage

dance_stop()

Value

TRUE if logging was taking place, otherwise FALSE (invisibly).

Examples

## Not run:

# Each expression adds a row to the tibble that tracks the execution of
# your R code.
x <- 7
x * 4

# This stops recording your R session.
dance_stop()

## End(Not run)
