available_templates

In the following you can find a comprehensive visualization of all the possible templates that you can access using pie_bake(), pie_bake_pro(), bubble_blow() and an example of the usage of pie_addimages().
Please note that the quality of the images is deliberately reduced compared to the classic quality of the function outputs for issues related to the size of the files.

Available templates for pie_bake()

A fairly simple data frame with 5 groups will be considered. Percentages will be displayed (i.e. the argument perc will be fixed to TRUE), with the title corresponding to the template name and a generic group name (i.e. “groups”).

The same for the pie_bake_pro() function can be found by scrolling down.

ex <- data.frame(
  LETTERS[1:5],
  c(65, 24, 54, 12, 43)
)

for(i in pie_template_list){
  print(pie_bake(ex, template = i, perc = TRUE, title = i))
}

Available templates for pie_bake_pro()

Here we don’t have to set the argument perc (there are some templates that display percentages anyways).

ex <- data.frame(
  LETTERS[1:5],
  c(65, 24, 54, 12, 43)
)

for(i in pie_template_list_pro){
  print(pie_bake_pro(ex, template = i, title = i))
}

Available templates for bubble_blow()

Below you can see the different templates available for the function bubble_blow() that allows the user to easily create cool circular packing charts.

A fairly simple data frame with 10 groups will be considered. Percentages will be displayed below the group labels (i.e. the argument perc will be fixed to below), with the title corresponding to the template name.

exblow <- data.frame(
  LETTERS[1:8],
  c(33, 24, 54, 12, 43, 88, 66, 78)
)

available_templates_bub <- c("bub1", "bub2", "bub3", "bub4", "bub5")

for(i in available_templates_bub){
  print(bubble_blow(exblow, template = i, perc = "below", title = i))
}

Example of usage of pie_addimages()

At first, let’s create a list of jpeg images loaded using the function readJPEG (for optimal and fast results, the use of small files is recommended) :

img1 <- jpeg::readJPEG(system.file("img", "logo.jpeg", package="tastypie"))
img2 <- jpeg::readJPEG(system.file("img", "parents.jpeg", package="tastypie"))
img3 <- jpeg::readJPEG(system.file("img", "bob.jpeg", package="tastypie"))
img4 <- jpeg::readJPEG(system.file("img", "mark.jpeg", package="tastypie"))
imgs <- list(img1,img2,img3, img4)

Then, let’s create the ggplot object using pie_bake() (without focusing on the template or other specifications, since only labels and values will be used):

df <- data.frame(
  c("Mark fan", "My friend", "Tastypie logo", "My parents"),
  c(300, 250, 225, 325)
)
mypie <- pie_bake(df, template = "basic1")

Now it is possible to run ppie_addimages() using the list of the images and the created pie chart, selecting also the colours of the graph’s borders and labels:

pie_addimages(
  mypie = mypie,
  imglist = imgs,
  perc = "below",
  lbl_col = "red",
  border_col = "grey"
)

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
