The recommendation is that you download the latest version of this package from CRAN, as I am constantly updating this repository. If you do download from here, know that things may break sometimes

Installation

# From CRAN
install.packages(r2resize)

# OR from Github
library(devtools)
install_github("oobianom/r2resize")

# Load library and begin using functions
library(r2resize)

# JQuery is required for most of the functions to run effectively
add.JQuery() #optional: only add if the page does not automatically include JQuery

Screenshots:

Use in Rmarkdown or Quarto document to add resizing toolbar to images and tables on the page

Code:



r2resize::add.resizer(
  theme.color = "black",
  position = "top",
  font.size = "12px",
  font.color = "black",
  tables = TRUE,
  images = TRUE,
  line.color = "orange",
  line.height = 5,
  line.width = 200,
  default.image.width = "40%"
)

Use in Shiny, Rmarkdown or Quarto document

As of version 1.6, the flexCard() function

Output:

Code:

flexCard(
  image = c(bg = "image1.jpg", icon = "edit", title="Sample text 1",subtitle="A cool subtitle"),
  image = c(bg = "image2.jpg", icon = "fire", title="Another sample text",subtitle="Focused subt title"),

  image = c(bg = "image4.jpg"),
  border.color = "black",
