Vector creation with c() in R Programming - Step-by-Step Execution

Concept Flow - Vector creation with c()

Start

↓

Call c() with elements

↓

Combine elements into vector

↓

Return vector

↓

Use vector in code

The c() function takes elements and combines them into a single vector, which can then be used in your R code.

Execution Sample

R Programming

v <- c(1, 2, 3, 4)
print(v)

This code creates a vector with numbers 1 to 4 and prints it.

Execution Table

Step	Action	Input Elements	Resulting Vector	Output
1	Call c() with elements	1, 2, 3, 4	c(1, 2, 3, 4)
2	Assign vector to v	c(1, 2, 3, 4)	v <- c(1, 2, 3, 4)
3	Print vector v	v = c(1, 2, 3, 4)	c(1, 2, 3, 4)	[1] 1 2 3 4

💡 All elements combined into vector and printed

Variable Tracker

Variable	Start	After Step 1	After Step 2	Final
v	NULL	NULL	c(1, 2, 3, 4)	c(1, 2, 3, 4)

Key Moments - 2 Insights

Why does c(1, 2, 3, 4) create a vector and not a list?

Because c() combines elements into a vector by default, which is a simple sequence of values. Lists are created with list() in R.

What happens if elements are of different types, like c(1, "a", TRUE)?

c() converts all elements to a common type (usually character) to keep the vector consistent.

Visual Quiz - 3 Questions

Look at the execution table, what is the value of v after step 2?

A c(1, 2, 3, 4)

B NULL

C 1

D c(4, 3, 2, 1)

💡 Hint

Check the 'Resulting Vector' column in row for step 2 in execution_table

At which step is the vector printed to the console?

A Step 1

B Step 2

C Step 3

D No printing happens

💡 Hint

Look at the 'Output' column in execution_table to find when printing occurs

If you add a character element to c(1, 2, 3), what happens to the vector type?

A It stays numeric

B It becomes character

C It becomes logical

D It becomes a list

💡 Hint

Refer to key_moments about type conversion when mixing types in c()

Concept Snapshot

c() combines multiple elements into a vector.
Syntax: c(element1, element2, ...)
All elements become the same type.
Use c() to create simple vectors quickly.
Vectors are basic data structures in R.

Full Transcript

This example shows how the c() function in R creates a vector by combining elements. First, c() is called with numbers 1, 2, 3, and 4. Then the result is assigned to variable v. Finally, printing v shows the vector contents. The vector holds all elements in order and is printed as [1] 1 2 3 4. If elements have different types, c() converts them to a common type, usually character. This is important to remember when mixing types. The key steps are calling c(), assigning the vector, and printing it.
