Web17 dec. 2024 · Note that inside a function, you can have multiple arguments separated by a comma. Inside matrix(), the first argument is the vector c(-1, 2, 0, 3), the second is ncol = 2 and the third is nrow = 2. For all functions in RStudio, you can specify an argument by its order inside the function or by the name of the argument.

WebFirst, we have to create an example matrix in R: my_mat1 <- matrix (1, ncol = 2, nrow = 2) # Create example matrix my_mat1 # Print example matrix. By running the previous R programming syntax we have constructed Table 1, i.e. a matrix containing only the value 0. Let’s try to apply the solve function to this matrix: Web1 uur geleden · Data i'm using are separate in data frames by dimentions, so if there is an 2-variate time series I have 2 data frames each with the same number of columns (time … WebAfter loading the data frame in R, we can apply the nrow function as follows: nrow ( iris) # Number of rows # 150 The number of lines of the iris database is 150. Example 2: Using nrow in R with Condition Let’s assume we want to count the rows of the iris data set where the variable Sepal.Length is larger than 5. how to calculate annual simple interest
