more sparklines + formattable

assembled with blockbuilder.org

I wanted to iterate through a couple more of these examples before a CRAN submission of the sparkline htmlwidgets package. In this example, I tried to approach sparklines + formattable + dplyr in R slightly differently than in some of the other examples.

code in R

library(sparkline)
library(htmltools)
library(htmlwidgets)
library(dplyr)

mtcars %>%
  group_by(cyl) %>%
  summarise(
    hp = as.character(
      as.tags(
        sparkline(hp, type="box", chartRangeMin=0, chartRangeMax=400)
      )
    ),
    mpg = as.character(
      as.tags(
        sparkline(mpg, type="box", chartRangeMin=0, chartRangeMax=50)
      )
    )
  ) %>%
  formattable() %>%
  formattable::as.htmlwidget() %>%
  modifyList(
    list(dependencies = c(
      htmlwidgets:::getDependency("sparkline")
    ))
  )

mtcars %>%
  group_by(cyl) %>%
  summarise(
    hp = as.character(
      as.tags(
        sparkline(hp, type="box", chartRangeMin=0, chartRangeMax=400)
      )
    ),
    mpg = as.character(
      as.tags(
        sparkline(
          round(density(mpg,from=0,to=tail(pretty(mtcars$mpg),1))$y,2),
          type="line"
        )
      )
    )
  ) %>%
  formattable() %>%
  formattable::as.htmlwidget() %>%
  modifyList(
    list(dependencies = c(
      htmlwidgets:::getDependency("sparkline")
    ))
  )
