Examples

if (requireNamespace("ggplot2") && interactive()) {
## Create a new workbook
wb <- wb_workbook()

## Add a worksheet
wb$add_worksheet("Sheet 1", gridLines = FALSE)

## create plot objects
require(ggplot2)
p1 <- qplot(mpg,
  data = mtcars, geom = "density",
  fill = as.factor(gear), alpha = I(.5), main = "Distribution of Gas Mileage"
)
p2 <- qplot(age, circumference,
  data = Orange, geom = c("point", "line"), colour = Tree
)

## Insert currently displayed plot to sheet 1, row 1, column 1
print(p1) # plot needs to be showing
wb$add_plot(1, width = 5, height = 3.5, fileType = "png", units = "in")

## Insert plot 2
print(p2)
wb$add_plot(1, xy = c("J", 2), width = 16, height = 10, fileType = "png", units = "cm")
