Basic Syntax and Data Types
Here's an overview of the basic syntax and data types in the R programming language:
Basic Syntax in R:
Statements in R are typically written one per line.
Comments are marked with the "#" symbol, and they are ignored during code execution.
Assigning values to variables is done using the "<-" operator or the "=" sign.
Data Types in R:
Numeric:
Represents numeric values (integers or decimals).
Example: x <- 5 or y <- 3.14
Character:
Stores text or string values.
Example: name <- "John" or city <- 'New York'
Logical:
Holds boolean values (TRUE or FALSE).
Example: is_valid <- TRUE or is_complete <- FALSE
Factor:
Represents categorical variables with predefined levels.
Example: gender <- factor(c("Male", "Female", "Male"))
Vector:
Ordered collection of elements of the same data type.
Example: numbers <- c(1, 2, 3, 4, 5)
Matrix:
2-dimensional array with rows and columns.
Example: matrix(data = c(1, 2, 3, 4), nrow = 2, ncol = 2)
List:
Ordered collection of elements of different data types.
Example: my_list <- list(name = "Alice", age = 30, is_student = TRUE)
Data Frame:
Tabular structure for organizing data with rows and columns.
Example: data_frame <- data.frame(name = c("John", "Jane"), age = c(25, 30), city = c("London", "Paris"))
Understanding these basic syntax rules and data types is essential for writing and manipulating data effectively in R programming.
R in Real-world Applications
