- Open RStudio and click on the "File" menu.
- Select "Packages" from the drop-down menu.
- Click on the "Install" button to install the required packages.
- The required packages are:
- dplyr: A package for data manipulation and analysis.
- tidyr: A package for data transformation and manipulation.
- ggplot2: A package for data visualization.
- readr: A package for data cleaning and preprocessing.
- stringr: A package for string manipulation.
- lubridate: A package for date and time manipulation.
- readxl: A package for reading and writing Excel files.
- readr: A package for reading and writing CSV files.
- ggplot2: A package for data visualization.
- plotly: A package for interactive visualizations.
- shiny: A package for building web applications.
- tidyverse: A package for data analysis and visualization.
Step 5: Create a New R Script
To use R, you need to create a new R script. Here are the steps:
- Open RStudio and click on the "File" menu.
- Select "New Script" from the drop-down menu.
- In the "New Script" window, enter the following code:
# Load the required packages
library(dplyr)
library(tidyr)
library(ggplot2)
data <- data.frame(name = c("John", "Mary", "David"), age = c(25, 31, 42))
filtered_data <- data %>%
filter(age > 30)
grouped_data <- filtered_data %>%
group_by(age) %>%
summarise(mean_age = mean(age))
ggplot(grouped_data, aes(x = age, y = mean_age)) +
geom_point() +
labs(title = "Mean Age by Age Group", x = "Age", y = "Mean Age")
* Save the script by clicking on the "File" menu and selecting "Save As".
