Please Show an Example in R:
Find (or invent) some data (not from the “Data” directory supplied with EssentialR) and import it into R. (It is not a bad idea to include a commented line with units for each variable in your .txt or.csv file). a) What did you have to do to “clean it up” so it would read in? b) Are you satisfied with the console output of summary(yourdata)? Did all the variables import in the way (format) you thought they should? c) Include the output of summary(yourdata) and head(yourdata).
7. Convert Standard POS form to Canonical POS form.
(A+B)(A+ C)(B+C)
8. Given that F(a, b, c, d) = Σm(1, 3, 4, 6, 8, 9, 12),
(i) Write the product of maxterms (canonical POS) for F.
(ii) Write the canonical SOP and canonical POS for F.
1. Evaluate the following expression when A = 1, B = O, C = 1, D = 0
F = AB + CD + (A + B)C
2. Find F, the complement of function F, Write your answer using overbars.
F(W, X, Y, Z) = WX + YZ +XZ
3. Determine the truth table for the function
F = XY+XZ
4. Show with a truth table that the following is true:
