slickR Basics

Simple carousel

Let’s start easy: show the team logos one at a time

slickR(obj = nba_team_logo$uri, height = 100, width = "95%", slideId = 'ex1')
#> Warning: The `slickOpts` argument of `slickR()` is deprecated as of slickR 0.5.0.

Let’s remove the dots with the slickOpts argument

slickR(obj = nba_team_logo$uri, 
       slideId = 'ex2', 
       slickOpts = list(dots = FALSE), 
       height = 100, 
       width = "95%")

There are many more settings you can define, such as autoplay. For all the settings go to slick.js homepage

slickR(
  obj = nba_team_logo$uri,
  slideId = 'ex3',
  slickOpts = list(dots = TRUE,autoplay = TRUE),
  height = 100, 
  width = "95%"
)

Grouped Images

There are players on each team, so lets group the starting five together and have each dot correspond with a team:

opts <- list(initialSlide = 0, 
     slidesToShow = 5, 
     slidesToScroll = 5,
     focusOnSelect = TRUE, 
     dots = TRUE)

slickR(nba_player_logo$uri,
       slideId = 'ex4',
       slickOpts = opts,
       height = 100, 
       width = "95%")

Adding Links

You can add links to each element in the slide using the objLinks parameter.

slickR(nba_player_logo$uri,
       slideId = 'ex5',
       objLinks = list(nba_player_logo$player_home), 
       slickOpts = opts,
       height = 100, 
       width = "95%")

Replacing the dots

Sometimes the dots won’t be informative enough so we can switch them with an HTML object, such as text or other images. We can pass to the customPaging argument javascript code using the htmlwidgets::JS function.

cP1 <- htmlwidgets::JS("function(slick,index) {
                            return '<a>'+(index+1)+'</a>';
                       }")

opts <- list(
    initialSlide = 0,
    slidesToShow = 5,
    slidesToScroll = 5,
    focusOnSelect = TRUE,
    dots = TRUE,
    customPaging = cP1
    )

slickR(
  obj = nba_player_logo$uri,
  dotObj = nba_team_logo$uri,
  slideId = 'ex6',
  slickOpts = opts,
  height = 100,
  width = "95%"
) 

cP2 <- JS("function(slick,index) {
          return '<a><img src= ' + dotObj[index] + '  width=100% height=100%></a>';
          }")

opts <- 
  list(
    initialSlide = 0,
    slidesToShow = 5,
    slidesToScroll = 5,
    focusOnSelect = TRUE,
    dots = TRUE,
    customPaging = cP2
  )

slick <- slickR(
  obj = nba_player_logo$uri,
  dotObj = nba_team_logo$uri,
  slideId = 'ex7',
  slickOpts = opts,
  height = 100,
  width = "95%"
) 


# Putting it all together in one slickR call
s2 <- htmltools::tags$script(
  sprintf("var dotObj = %s", jsonlite::toJSON(nba_team_logo$uri))
)

htmltools::browsable(htmltools::tagList(s2, slick))

Synching Carousels

There are instances when you have many outputs at once and do not want to go through all, so you can combine two carousels one for viewing and one for searching.

opts <- list(
  # 'up' options
    list(slidesToShow = 1, slidesToScroll = 1),
  # 'down' options
    list(dots = FALSE, 
         slidesToScroll = 1, 
         slidesToShow = 5,
         centerMode = TRUE, 
         focusOnSelect = TRUE)
)

synch_map <- expand.grid(list('up','down'),stringsAsFactors = FALSE)

slickR(rep(nba_player_logo$uri,2),
       slideIdx = replicate(2,seq_along(nba_player_logo$uri),simplify = FALSE),
       slideId =  c('up','down'),
       objLinks = list(up = nba_player_logo$player_home,down = NULL),
       synchSlides = synch_map,
       slideType = rep('img',2),
       slickOpts = opts,
       height = 100, 
       width = "90%")

Adding a Caption to Image

You can add a caption to an image by synching two carousels, where the upper is the content (e.g. image) and the bottom is the caption (p)

slickR(
  obj         = c(nba_player_logo$uri[1:2],
                  glue::glue('<p>{nba_player_logo$name[1:2]}</p>')),
  slideType   = c('img','p'),
  slideId     = c('img','cap'),
  slideIdx    = list(c(1,2),c(3,4)),
  synchSlides = expand.grid(list('img','cap'),stringsAsFactors = FALSE),
  height      = 100,
  slickOpts   = list(list(dots=FALSE),list(dots=TRUE,arrows=FALSE))
)
