Print htmlwidgets to HTML Result Inside a Function in R
HTML widgets are interactive graphical objects that can be embedded in web pages. They enable you to use R code to produce animations, visualizations, and other interactive elements. These widgets can be easily made and used in R Programming Language with the htmlwidgets package. We’ll go over how to print an HTML widget inside of an R function in this article.
Before printing an HTML widget inside a function, it is crucial to comprehend a few fundamental ideas. First, R’s htmlwidgets package offers a collection of functions for building HTML widgets. Second, we’ll use the saveWidget method from the htmlwidgets package to print the widget inside a function. Finally, a message stating that the widget has been saved will be printed using the cat function.
Example 1
Step 1
First, install the ‘htmlwidgets’ library to use.
install.packages(“htmlwidgets”)
Step 2
The htmlwidgets package must be loaded. The htmlwidgets package should first be loaded into your R environment. Run the following code in your R console to accomplish this:
R
library (htmlwidgets) |
Step 3
Construct the function: Make a function that prints the HTML widget next. The saveWidget function is used by this function to save an HTMLwidget object as an HTML file. As an illustration of the function:
R
print_htmlwidget <- function (x) { htmlwidgets:: saveWidget (x, file = "widget.html" ) cat ( "HTML widget saved to widget.html\n" ) } |
Step 4
Use print_htmlwidget with the dygraph.
R
library (dygraphs) dygraph (nhtemp, main = "City Temperature" ) %>% print_htmlwidget () |
Output:
Example 2:
R
library (htmlwidgets) print_htmlwidget <- function (x) { htmlwidgets:: saveWidget (x, file = "Histogram.html" ) cat ( "HTML widget saved to Histogram.html\n" ) } X = rnorm (500, mean=20, sd=10) hist (X, breaks = 10, main = "Histogram" , xlab = "Bins" ) %>% print_htmlwidget () |
