How to print Pascal's Triangle Pattern in R

How to print Pascal's Triangle Pattern in R ?

Answer

To print Pascal's Triangle Pattern in R, you can use a combination of loops and conditional statements to calculate the values for each row based on the binomial coefficient formula.

✐ Examples

1 Pascal's Triangle Pattern

In this example,

We use a variable n to represent the number of rows in Pascal's triangle.
We initialize a matrix pascal to store the triangle values.
We use nested loops to calculate and store the values using the binomial coefficient formula.
We print the triangle values using a formatted output.

R Program

# Function to print Pascal's Triangle
printPascalsTriangle <- function(n) {
  pascal <- matrix(0, n, n)
  for (i in 1:n) {
    for (j in 1:i) {
      if (j == 1 || j == i) {
        pascal[i, j] <- 1
      } else {
        pascal[i, j] <- pascal[i - 1, j - 1] + pascal[i - 1, j]
      }
      cat(pascal[i, j], " ", sep = "", end = "")
    }
    cat("\n")
  }
}

# Usage
rows <- 5
printPascalsTriangle(rows)

Output
