na.print: indicates NA values output format

Example 1:

# R program to illustrate
# print function

# Creating a data frame
x <- cars[1:5, ]

# Calling the print() function
# to print the above data frame
print(x)

Output:

  speed dist
1     4    2
2     4   10
3     7    4
4     7   22
5     8   16

Example 2:

# R program to illustrate
# print function

# Initializing a number
x <- 15 / 7

# Calling the print() function
# using digits parameter
print(x, digits = 2)
print(x, digits = 3)
print(x, digits = 4)

Output:

[1] 2.1
[1] 2.14
[1] 2.143 

Example 3:

# R program to illustrate
# print function

# Creating a matrix
x <- matrix(c(2, NA, 5, NA, 8, NA, 22, 67, 43),
               nrow = 3, byrow = TRUE)

# Calling the print() function
# using na.print parameter
print(x, na.print = "")

Output:

     [, 1] [, 2] [, 3]
[1, ]    2         5
[2, ]         8     
[3, ]   22   67   43
