PLEASE USE PROGRAMMING LANGUAGE OF R
Generate a random 5x5 matrix whose entries are the numbers 1,2, ... 25, but in random positions, using the following code: ```{r} set.seed(27) #set the seed for the random number generator x=matrix(sample(1:25), byrow=T,ncol=5) # x ```
As you can see, on my system, I get the following input matrix:
[,1] [,2] [,3] [,4] [,5] [1,] 5 18 22 9 8[2,] 19 16 1 24 23
[3,] 17 25 3 11 21
[4,] 15 10 6 7 4
[5,] 13 20 14 12 2
Then, using a pair of nested for loops, loop over the positions in the matrix x, and if the associated element of x is odd, replace the element by its negative.
```{r} #for loop involving i { # for loop involving j { # x[i,j]=ifelse(x[i,j]%%2==1, -x[i,j], something here for odd # elements ) #}} #print(x) ```
Your answer should be equivalent to the following answer (which is valid for the input matrix shown above)
-5 18 22 -9 8 -19 16 -1 24 -23 -17 -25 -3 -11 -21 -15 10 6 -7 -4 -13 20 14 12 2
Use your own input matrix instead, if different.
