# Calling the toString() function toString (x)
|
Output :
[1] "GFG, Geeks, GeeksforGeekss"
Example 2: Formatting with toString() Function in R Language
R
# R program to illustrate # toString function # Initializing a string vector x <- c ( "GFG" , "Geeks" , "GeeksforGeekss" )
# Calling the toString() function toString (x, width = 2)

[1] "GF...." [1] "GFG, ...." [1] "GFG, G...."
Example 3: Convert Matrix to String in R
R
# Matrix having 3 rows and 3 columns # filled by a single constant 5 mat <- ( matrix (5, 3, 3))
print (mat)
str <- toString (mat)

print (str)
|
Output:
[,1] [,2] [,3] [1,] 5 5 5 [2,] 5 5 5 [3,] 5 5 5 [1] "String" [1] "5, 5, 5, 5, 5, 5, 5, 5, 5"
