Tips & tricks

Count with percent

A classic count() returns the number of observations.

data <- use_data_penguins()
data %>% count(island)
#> # A tibble: 3 x 2
#>   island        n
#>   <fct>     <int>
#> 1 Biscoe      168
#> 2 Dream       124
#> 3 Torgersen    52

To add percent values, simply use count_pct() from {explore}.

data %>% count_pct(island)
#> # A tibble: 3 x 4
#>   island        n total   pct
#>   <fct>     <int> <int> <dbl>
#> 1 Biscoe      168   344  48.8
#> 2 Dream       124   344  36.0
#> 3 Torgersen    52   344  15.1

Add id

data %>% glimpse()
#> Rows: 344
#> Columns: 8
#> $ species           <fct> Adelie, Adelie, Adelie, Adelie, Adelie, Adelie, Adel~
#> $ island            <fct> Torgersen, Torgersen, Torgersen, Torgersen, Torgerse~
#> $ bill_length_mm    <dbl> 39.1, 39.5, 40.3, NA, 36.7, 39.3, 38.9, 39.2, 34.1, ~
#> $ bill_depth_mm     <dbl> 18.7, 17.4, 18.0, NA, 19.3, 20.6, 17.8, 19.6, 18.1, ~
#> $ flipper_length_mm <int> 181, 186, 195, NA, 193, 190, 181, 195, 193, 190, 186~
#> $ body_mass_g       <int> 3750, 3800, 3250, NA, 3450, 3650, 3625, 4675, 3475, ~
#> $ sex               <fct> male, female, female, NA, female, male, female, male~
#> $ year              <int> 2007, 2007, 2007, 2007, 2007, 2007, 2007, 2007, 2007~

To add an id variable, simply use add_var_id() from {explore}.

data %>% add_var_id() %>% glimpse()
#> Rows: 344
#> Columns: 9
#> $ id                <int> 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 1~
#> $ species           <fct> Adelie, Adelie, Adelie, Adelie, Adelie, Adelie, Adel~
#> $ island            <fct> Torgersen, Torgersen, Torgersen, Torgersen, Torgerse~
#> $ bill_length_mm    <dbl> 39.1, 39.5, 40.3, NA, 36.7, 39.3, 38.9, 39.2, 34.1, ~
#> $ bill_depth_mm     <dbl> 18.7, 17.4, 18.0, NA, 19.3, 20.6, 17.8, 19.6, 18.1, ~
#> $ flipper_length_mm <int> 181, 186, 195, NA, 193, 190, 181, 195, 193, 190, 186~
#> $ body_mass_g       <int> 3750, 3800, 3250, NA, 3450, 3650, 3625, 4675, 3475, ~
#> $ sex               <fct> male, female, female, NA, female, male, female, male~
#> $ year              <int> 2007, 2007, 2007, 2007, 2007, 2007, 2007, 2007, 2007~

User defined report

Create a user defined report (RMarkdown template) to explore your own data.

create_notebook_explore(
  output_dir = tempdir(),
  output_file = "notebook-explore.Rmd")

Data Dictionary

Create a Data Dictionary of a data set (Markdown File data_dict.md)

iris  %>%  data_dict_md(output_dir = tempdir())

Add title, detailed descriptions and change default filename

description <- data.frame(
                  variable = c("Species"), 
                  description = c("Species of Iris flower"))
data_dict_md(iris, 
             title = "iris flower data set", 
             description =  description, 
             output_file = "data_dict_iris.md",
             output_dir = tempdir())

Color

You can make your explore-plot more colorful

data <- use_data_penguins()
data |> explore(flipper_length_mm, color = "lightskyblue")

data |>
  drop_obs_with_na() |> 
  explore(flipper_length_mm, bill_length_mm, 
          target = sex, color = c("deeppink", "blue"))

You can even mix your own colors

colors <- mix_color("blue", n = 5)
colors
#> [1] "#AAAAFF" "#5555FF" "#0000FF" "#0000AA" "#000055"

show_color(colors)

colors <- mix_color("gold", "red", n = 4)
colors
#> [1] "#FFD700" "#FF8F00" "#FF4700" "#FF0000"

show_color(colors)

Or use some of the predefined colors in {explore}

get_color()
#> $a1
#> greylight       red      blue     black  greydark 
#> "#a3a9b0" "#d32c1c" "#5dbcd2" "#000000" "#868e96"
