As you could probably guess, there are different types of objects in R. As we discussed previously, when you load or create data in R, you create objects. Otherwise, the usual coercion hierarchy (logical < integer < double < complex) will be used, e.g., all-logical data frames will be coerced to a logical matrix, mixed. The method for data.tables will return a character matrix if there are only atomic columns and any non-(numeric/logical/complex) column, applying as.vector to factors and format to other non-character columns. It dispatches to as.matrix.data.table if its x argument is a data.table. As.matrix is a generic function in base R.
![]() Matrix Function In R How To Use TheseEach of these object types is a different way to store data. If you used a named argument, you can specify just. For example, > mymat matrix(1:12,4,3) > mymat ,1 ,2 ,3 1, 1 5 9 2, 2 6 10 3, 3 7 11 4, 4 8 12 The last two arguments to matrix tell it the number of rows and columns the matrix should have. data frames (or similar objects, like last lecture’s tibble)The matrix function takes a vector and makes it into a matrix in a column-wise fashion. Also, we will see how to use these functions of the R matrix with the help of examples.![]() ![]()
