Size of the shiny app

Source: R/size.R

The size of shiny app is a sum of dependencies packages and the app directory. The app dependencies packages are checked recursively, and only in local repository. The default arguments setup is recommended.

app_size(
  path = ".",
  fields = c("Depends", "Imports", "LinkingTo"),
  lib.loc = .libPaths(),
  recursive = TRUE
)

Arguments

path

character path to the shiny app. Default: "."

fields

character vector listing the types of dependencies, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances"). Character string "all" is shorthand for that vector, character string "most" for the same vector without "Enhances", character string "strong" (default) for the first three elements of that vector. Default: c("Depends", "Imports", "LinkingTo")

lib.loc

character vector of search paths with local packages. Default: .libPaths()

recursive

logical if to assess the dependencies recursively. Default: TRUE

Value

numeric size in bytes, to get MB ten divide by 10**6.

Note

renv package has to be installed. base packages (pacs::pacs_base()) are not taken into account.

Examples

if (FALSE) { # \dontrun{
library(renv)
# Please update the path to the shiny app
cat(pacs::app_size(system.file("examples/04_mpg", package = "shiny")) / 10**6, "MB")
} # }
