Assuming the name of your data frame is flavors_df, the code chunk which will allow review of the structure of the data frame is colnames(flavors_df).
<h3>
What is Code chunk?</h3>
This is referred to a a runable piece of R code and helps to reduce incidents of mismatch pertaining to the commentary in a paper and the results being discussed.
In the case of a data frame which is flavors_df, the appropriate code chunk is colnames(flavors_df) which allow for extensive review of the item with the barest minimal error which is why it was chosen as the most appropriate choice.

Answer:
see explaination
Explanation:
MATLAB script:
% MATLAB script that calculates reciprocal Fibonacci constant Ψ
% Initial Values
a0 = 1;
a1 = 1;
% Looping variable
i = 2;
% Reading n value from user
n = input(' Enter n value: ');
% Initializing sum
sum = (1/a0) + (1/a1);
% Loop till i reaches n value
while i <= n
% Finding term in Fibnocii series
a2 = a0 + a1;
% Accumulating Sum
sum = sum + (1/a2);
% Updating previous terms
a0 = a1;
a1 = a2;
% Incrementing loop variable
i = i + 1;
endwhile
% Printing result
printf("\n Reciprocol Fibnocii Constant: %f \n", sum);

Answer:
True
Explanation:
When using databases in a project, not everyone has the same access level, e.g the database admin may have the highest level of access (access to data on live mode), the software testers have their own level of access (access to data on test mode) and so on.
Answer:
The answer is "Option d".
Explanation:
In networking, NAT refers to the Network Address Translation. This process is used to translate computer IP addresses into a single IP address in your local network. It allows private IP networks to connect to the Internet using unregistered IP addresses. and other options are incorrect that can be described as follows:
- In option a, SSL stands for Secure Sockets Layer. It is used in transmission of documents or data over a network that's why it is not correct.
- In option b, RADIUS stands for Remote Authentication Dial-In User Service. It is used to manage the data on a network.
- In option c, PPTP stands for Point-to-Point Tunneling Protocol. It is used to provide a set of rules for communicating through a network that's why it is not correct.
Answer:
B
Explanation:
engineers design and carry out test cases and evaluate exit criteria (by following the scope set in the planning phase). They create bug reports describing detected defects and report to the stakeholders on the test findings and the completion status. Testing may be repeated to check for errors.
