Answer:
The solution code is written in R script.
- #string variable
- character_str<- "Hello World"
- #logical variable
- logic <- a > b
- #Missing value
- myVec <-c(1, 2, 3, NA)
- #Use class to check data type
- class(character_str)
- class(logic)
- class(myVec)
Explanation:
A string variable is a variable that hold a string (the letters enclosed within quotation marks) (Line 2)
A logical variable is a variable that hold a logical value (either True or False). The logical value is created by comparing two variables (Line 5).
In R, missing value is an unknown value which is represented by NA symbol (Line 8).
We can use in-built method <em>class </em> to check for the variable type in R (Line 11-13). For example, the output of <em>class(character_str)</em> is "<em>character</em>"
Answer:
while (quantity >= 50)
Explanation:
Required
Stop when quantity is less than 50
To do this, we make use of a while statement and the syntax is:
while (condition){ }
If the loop should stop when quantity is less than 50; then it means the loop would continue when quantity is greater or equal to 50
So, we have:
while (quantity >= 50)
Answer:
C
Explanation:
In simple words, data mining is defined as a process used to extract usable data from a larger set of any raw data. It implies analysing data patterns in large batches of data using one or more software.
what...? how is this a question??
Answer:
The answer is "new version of application provides more easy to use".
Explanation:
- In computer science, an application is a program, that is installed on the computer. There are many types of application software, that are "gaming software, working software, programming software, etc." At the end of time users want some new things in software to know users need programmer developed new versions of the software.
- The update usually improves the device or service in its current version, whilst an improvement is an entirely new version. Installation is usually free and easy. You also have to wait for updates that are difficult to install.
