- Works seamlessly with the %>% (pipe) operator for readable and concise code.
Example:
library(dplyr)
data %>%
filter(value > 10) %>%
- select(name, value)
2. ggplot2: Create Stunning Visualizations
- Purpose: Data visualization
- Why It’s Great:
- Implements the grammar of graphics for highly customizable plots.
- Supports a wide variety of charts like scatter plots, bar plots, and heatmaps.
Example:
library(ggplot2)
ggplot(data, aes(x = category, y = value)) +
- geom_bar(stat = “identity”)
3. tidyr: Tidy Your Data
- Purpose: Data cleaning and reshaping
- Why It’s Great:
- Converts messy datasets into a tidy format.
- Functions like gather, spread, and pivot_longer make reshaping intuitive.
Example:
library(tidyr)
data %>%
- pivot_longer(cols = starts_with(“Q”), names_to = “Question”, values_to = “Response”)
4. readr: Seamless Data Import
- Purpose: Data import
- Why It’s Great:
- Quickly reads large datasets in formats like CSV and TSV.
- Functions like read_csv and read_delim are optimized for speed.
Example:
library(readr)
- data <- read_csv(“data.csv”)
5. data.table: High-Performance Data Manipulation
- Purpose: Data manipulation
- Why It’s Great:
- Handles large datasets with unmatched speed.
- Combines data manipulation and aggregation in one concise syntax.
Example:
library(data.table)
dt <- data.table(data)
- dt[value > 10, .(mean_value = mean(value))]
6. caret: Machine Learning Made Easy
- Purpose: Machine learning
- Why It’s Great:
- Offers tools for data preprocessing, model training, and validation.
- Supports a wide range of algorithms and cross-validation methods.
Example:
library(caret)
- model <- train(target ~ ., data = training_data, method = “rf”)
7. plotly: Interactive Visualizations
- Purpose: Interactive visualizations
- Why It’s Great:
- Allows the creation of interactive, web-based plots.
- Ideal for presentations and dashboards.
Example:
library(plotly)
- plot_ly(data, x = ~category, y = ~value, type = ‘bar’)
8. shiny: Build Interactive Dashboards
- Purpose: Web application development
- Why It’s Great:
- Enables rapid development of interactive dashboards and web applications.
- Combines R’s analytical power with a user-friendly interface.
Example:
library(shiny)
ui <- fluidPage(
titlePanel(“My Shiny App”),
sidebarLayout(
sidebarPanel(),
mainPanel()
)
)
server <- function(input, output) {}
- shinyApp(ui = ui, server = server)
9. lubridate: Simplify Date-Time Manipulations
- Purpose: Date-time manipulation
- Why It’s Great:
- Makes working with dates and times intuitive.
- Functions like ymd, hms, and floor_date simplify operations.
Example:
library(lubridate)
- dates <- ymd(“2023-01-01”)
10. stringr: Handle Strings with Ease
- Purpose: String manipulation
- Why It’s Great:
- Provides a cohesive set of functions for string operations.
- Handles pattern matching, extraction, and replacement effortlessly.
Example:
library(stringr)
- str_detect(text, “pattern”)
