R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

# Load the ggplot2 library
library(ggplot2)

# Aggregate the count of each species
species_count <- table(iris$Species)

# Convert the table to a data frame
species_df <- as.data.frame(species_count)
species_df$Species <- rownames(species_df)

# Create a bar graph
ggplot(species_df, aes(x = Species, y = Freq)) +
  geom_bar(stat = "identity", fill = "skyblue") +
  labs(title = "Bar Graph of Iris Species Counts", x = "Species", y = "Count")

# Load the ggplot2 library
library(ggplot2)

# Count the number of each species
species_count <- table(iris$Species)

# Create a pie chart
ggplot(data = as.data.frame(species_count), aes(x = "", y = Freq, fill = Var1)) +
  geom_bar(stat = "identity") +
  coord_polar(theta = "y") +
  labs(title = "Pie Chart of Iris Species Proportions", fill = "Species") +
  scale_fill_manual(values = c("setosa" = "red", "versicolor" = "green", "virginica" = "blue"))

# Load the ggplot2 library
library(ggplot2)

# Create a scatterplot for the Iris dataset
ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) +
  geom_point() +
  labs(title = "Scatterplot of Sepal Length vs. Sepal Width", x = "Sepal Length", y = "Sepal Width")

# Load the ggplot2 library
library(ggplot2)

# Create a box plot for the Iris dataset
ggplot(iris, aes(x = Species, y = Sepal.Length, fill = Species)) +
  geom_boxplot() +
  labs(title = "Box Plot of Sepal Length by Species", x = "Species", y = "Sepal Length")

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
