embed_img {reactablefmtr}

Embed image from web to cells in a column

Description

The 'embed_img()' function adds images obtained from the web to a column within reactable. It should be placed within the cell argument in reactable::colDef.

Usage

embed_img(
  data,
  height = 24,
  width = 24,
  horizontal_align = "center",
  label = NULL,
  label_position = "right"
)

Arguments

data

Dataset containing URL's to images

height

A value given for the height of the image in px. Default height is 24px.

width

A value given for the width of the image in px. Default width is 24px.

horizontal_align

The horizontal alignment of the image within a cell. Options are "left", "right", or "center". Default is "center".

label

Optionally assign a label to the image from another column. Default is set to NULL or no label.

label_position

Position of label relative to image. Options are "right", "left", "below", or "above". Default is right.

Value

a function that renders an image to a column containing a valid web link.

Examples

## If no image links are in the original dataset, you need to assign them like so:
library(dplyr)
data <- iris %>%
 mutate(
 img = case_when(
 Species == "setosa" ~
 "https://upload.wikimedia.org/wikipedia/commons/d/d9/Wild_iris_flower_iris_setosa.jpg",
 Species == "versicolor" ~
 "https://upload.wikimedia.org/wikipedia/commons/7/7a/Iris_versicolor.jpg",
 Species == "virginica" ~
 "https://upload.wikimedia.org/wikipedia/commons/9/9f/Iris_virginica.jpg",
 TRUE ~ "NA"))

## Then use embed_img() to display images
reactable(data,
columns = list(
 img = colDef(cell = embed_img())))

## By default, images are given a size of 24px by 24px,
## but you can adjust the size using height and width:
reactable(data,
columns = list(
 img = colDef(cell = embed_img(height = 50, width = 45))))

## Optionally assign a label to the image from another column
reactable(data,
columns = list(
 img = colDef(cell = embed_img(data, label = "Species"))))
