The goal of PackageR is to to help users better understand their package. When developing R packages, it’s easy to lose track of the scale of the project. This package provides functions to give developers a better insight into the number of functions, files, and their length. From here, developers can work to identify overly-complex functions or chokepoints and eventually write cleaner code.
You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("ARawles/packageR")To get a high-level understanding of the functions and files in your
package, use the plot_ functions. These functions will produce ggplot2
graphics showing you a bit more about your package:
plot_function_length()
To access the data in a more raw format, use the list_functions() and
list_x_files() functions:
list_functions()
#> [[1]]
#> [[1]]$name
#> [1] "file_length"
#>
#>
#> [[2]]
#> [[2]]$name
#> [1] "function_body"
#>
#>
#> [[3]]
#> [[3]]$name
#> [1] "function_info"
#>
#>
#> [[4]]
#> [[4]]$name
#> [1] "function_length"
#>
#>
#> [[5]]
#> [[5]]$name
#> [1] "function_list_to_tibble"
#>
#>
#> [[6]]
#> [[6]]$name
#> [1] "language_to_character"
#>
#>
#> [[7]]
#> [[7]]$name
#> [1] "library.dynam.unload"
#>
#>
#> [[8]]
#> [[8]]$name
#> [1] "list_functions"
#>
#>
#> [[9]]
#> [[9]]$name
#> [1] "list_r_files"
#>
#>
#> [[10]]
#> [[10]]$name
#> [1] "list_to_function_list"
#>
#>
#> [[11]]
#> [[11]]$name
#> [1] "plot_function_length"
#>
#>
#> [[12]]
#> [[12]]$name
#> [1] "system.file"
#>
#>
#> [[13]]
#> [[13]]$name
#> [1] "total_function_count"
#>
#>
#> [[14]]
#> [[14]]$name
#> [1] "total_function_length"
list_r_files()
#> [1] "man-roxygen/pkg.R" "R/files.R" "R/functions.R"
#> [4] "R/ne_utility.R" "R/plot.R" "R/total.R"
#> [7] "R/utility.R"By setting the info parameter to TRUE, you can retrieve more
information about the functions:
list_functions(info = TRUE)[[1]]
#> $name
#> [1] "file_length"
#>
#> $body
#> {
#> length(readLines(path))
#> }
#>
#> $length
#> [1] 1
