Introduction

This package builds the download button in R Markdown using bsplus, and it was inspired on this post from Yihui Xie.

✅ {downloadthis} now uses font-awesome icons v.6.5.2

Usage

Data frames, lists, or any R object

library(downloadthis)

mtcars %>%
  download_this(
    output_name = "mtcars data set",
    output_extension = ".csv",
    button_label = "Download data",
    button_type = "warning",
    has_icon = TRUE,
    icon = "fa fa-save"
  )

vector_example <- 1:10
linear_model <- lm(mpg ~ gear, data = mtcars)

list(mtcars, iris, vector_example, linear_model) %>%
  download_this(
    output_name = "datasets, vector, and linear model",
    output_extension = ".rds",
    button_label = "Download as rds",
    button_type = "success",
    has_icon = TRUE,
    icon = "fa fa-save"
  )

Web address

## Link in Github repo
download_link(
  link = "https://github.com/fmmattioni/downloadthis/raw/master/inst/example/file_1.pdf",
  button_label = "Download pdf file",
  button_type = "danger",
  has_icon = TRUE,
  icon = "fa fa-save",
  self_contained = FALSE
)

Local files

## One file example
download_file(
  path = system.file("assets/css/all.min.css", package = "downloadthis"),
  output_name = "CSS file from downloadthis",
  button_label = "Download css file",
  button_type = "danger",
  has_icon = TRUE,
  icon = "fa fa-save",
  self_contained = FALSE
)

Local directory

## Directory path as an example
download_dir(
  path = system.file("assets", package = "downloadthis"),
  output_name = "example dir",
  button_label = "Download directory",
  button_type = "success",
  has_icon = TRUE,
