Data Manipulation

Create a vector

my_vector <- c(1, 2, 3, 4, 5)

Create a data frame

df <- data.frame(Name = c("Alice", "Bob", "Charlie"), Age = c(25, 30, 22))

Subset data

subset_df <- df[df$Age > 25, ]

Merge data frames

merged_df <- merge(df1, df2, by = "ID")

Sort data

sorted_df <- df[order(df$Column), ]

Data sampling

sample_data <- sample(my_vector, size = 5, replace = TRUE)

Data reshaping

transposed_matrix <- t(my_matrix)
