I have a list of 300 plots and want one PowerPoint slide to show one plot (300 slides). What's the best way to achieve this?
A toy example using the built-in iris dataset to create a list of plots:
purrr::map(names(iris[,-5]), function(col_name){
plot = iris %>%
ggplot(aes(x = !!as.name(col_name))) +
geom_histogram()
return(plot)
})
I hope to create PowerPoint slides with one plot on each slide.
I will be using the iris data set, which is a built-in data set often used to populate example code.
With the following code in a Rmd file:
---
title: "Test_PowerPoint"
author: "KoenV"
date: '2022-06-30'
output: powerpoint_presentation
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```
```{r include=FALSE, warning=FALSE, message=FALSE}
library(tidyverse)
library(purrr)
```
```{r, iris, fig.cap="A scatterplot.", echo=FALSE, warning=FALSE, message=FALSE}
## your code
purrr::map(names(iris[,-5]), function(col_name){
plot = iris %>%
ggplot(aes(x = !!as.name(col_name))) +
geom_histogram()
return(plot)
})
```
And after hitting the "knit" button, you will see a PowerPoint presentation appearing, with the following lay-out:
Please let me know, whether this is what you wanted.
