To find the maximum value in each matrix stored in an R list, we can follow the below steps −First of all, create a list of matrices.Then, use max function along with lapply function to find the maximum of each matrix.Create the list of matricesUsing matrix function to create multiple matrices and stored them in a list using list function − Live DemoM1

To divide matrix row values by row median in R, we can follow the below steps −First of all, create a matrix.Then, use apply function to divide the matrix row values by row median.Create the matrixLet's create a matrix as shown below − Live DemoM

To create a table of frequency for range of values in an R data frame column, we can follow the below steps −First of all, create a data frame.Then, use table function with cut function to create the table of frequency for range of values.Example 1Create the data frameLet's create a data frame as shown below − Live Demox

To find the row minimum excluding zero in R data frame returning 0 if all 0, we can follow the below steps −First of all, create a data frame.Then, find the row minimum by excluding zero using if function with apply function.Example1Create the data frameLet's create a data frame as shown below − Live Demox1
