Biostatistics & Computational Analysis RSTUDIO
1. Write a program to take a positive whole number from user and do the following task:
(You are expected to write a simple, easy-to-follow function that does all the questions' assigned
tasks)
a. Separate all digits in the number and save them in a vector a
ay named “Info”.
. Check every digit you saved in “Info” is even or odd. For odd digit use “O” and for Even digit
use “E” to create another vector (named Odd_Even) of the same size of “Info”.
c. Check every digit you saved in “Info” is a prime or not a prime number. For the prime digit,
use “P” and for the Not Prime digit use “NP” to create another vector (named Prime_info) of the
same size of “Info”.
d. For number with more than 4 digits, find the minimum, maximum, mean, median, and
standard deviation of all digits saved in Info a
ay. Create a vector with the same size of “Info”
vector. Store the value of the calculated minimum, maximum, mean, median, and standard
deviation in the first five indices and fill the rest of the vector by zeros.
e. Combine vectors in Part A, B, C, and D (if it exists!) to define a data frame (Name:
Number_Information).
Export the data frame as an excel file (You may install some Packages!).
2. We have 365 days per year. Make a program to take the day number as an input and in return
give the following information:
1. To which month that day belongs to?
2. Day number in the month
3. Weekday
Example
3. Create a function to print squares of numbers in sequence and also calculate their summation:
1^2+2^2+3^2+4^2…….n^2
4. Create a ti
le containing only family and personal names, in that order. You do not need to assign
this ti
le or any others to variables unless explicitly asked to do so. However, as noted in the
introduction, you must use the pipe operator %>% and code that follows the tidyverse style guide.
5. Write a function called summarize_table that takes a title string and a ti
le as input and returns
a string that says something like, “title has # rows and # columns”.
Example, summarize_table('our table', person) should return the string "our table has 5 rows and 3
columns".
