The function count_percentage allows you to count the observations per
group and compute the associated percentage.
For instance, count_percentage will return the following for the iris dataset
# Load the library
library(utile)
# Count the percentage of Species in the iris dataset
count_percentage(iris, Species, digits = 1)## # A tibble: 3 x 3
## Species n percentage
## <fct> <int> <dbl>
## 1 setosa 50 33.3
## 2 versicolor 50 33.3
## 3 virginica 50 33.3
The function export_charts_ppt allows you to export a list of ggplots
into a PowerPoint file.
For instance:
# Load the libraries
library(utile)
library(ggplot2)
# Create an empty list to store the plots
listP <- list()
# Store a plot
listP[["first_chart"]] <- ggplot(data = iris) +
geom_point(mapping = aes(Sepal.Length, Petal.Length))
# Export the plots in a PowerPoint file named my_plots.pptx
export_charts_ppt(listP, export_path = "my_plots.pptx")
