R How to Convert a Matrix to a One-Dimensional Array (Example Code)
This tutorial shows how to convert a matrix to a vector object in the R programming language.
Creation of Example Data
data(iris) # Load and prepare example data iris_mat <- as.matrix(iris[ , 1:4]) head(iris_mat) # Return head of example data # Sepal.Length Sepal.Width Petal.Length Petal.Width # [1,] 5.1 3.5 1.4 0.2 # [2,] 4.9 3.0 1.4 0.2 # [3,] 4.7 3.2 1.3 0.2 # [4,] 4.6 3.1 1.5 0.2 # [5,] 5.0 3.6 1.4 0.2 # [6,] 5.4 3.9 1.7 0.4 |

Example: Applying c() Function to Convert Matrix to One-Dimensional Vector
iris_vec <- c(iris_mat) # Using c function in R iris_vec # Returning vector output # 5.1 4.9 4.7 4.6 5.0 5.4 4.6 5.0 4.4 4.9 5.4 4.8 4.8 4.3 5.8 5.7 5.4 5.1 ... |
iris_vec <- c(iris_mat) # Using c function in R iris_vec # Returning vector output # 5.1 4.9 4.7 4.6 5.0 5.4 4.6 5.0 4.4 4.9 5.4 4.8 4.8 4.3 5.8 5.7 5.4 5.1 ...
