Step-by-Step Guide:

  1. First, load your dataset into R using the read.csv() function or similar.
  2. Identify the columns that you want to combine. For example, let's say you have columns for "First Name" and "Last Name" and you want to combine them into a single column for "Full Name".
  3. Use the paste() function to combine the columns. The basic syntax is paste(column1, column2, sep = " "), where column1 and column2 are the names of the columns you want to combine, and sep = " " specifies the separator between the columns (in this case, a space).
  4. Create a new column in your dataset using the combined values. You can do this using the $ operator and the name of the new column you want to create.

Example:


# Load dataset
data <- read.csv("mydata.csv")

# Combine columns for "First Name" and "Last Name"
data$Full_Name <- paste(data$First_Name, data$Last_Name, sep = " ")

# View updated dataset
head(data)

By following these simple steps and using the paste() function, you can quickly and easily combine multiple columns in R to create new variables in your dataset.
