Basic String Operations in R
1. nchar() is used to find length of a string
Code:
nchar(“Introduction to R”)
Output:
[1] 17
2. length() returns number of elements in object. So for single string it will return 1
Code:
length(“Introduction to R”)
Output:
[1] 1
3. paste() is used to concatenate strings. By default, paste() inserts a single space between pairs of strings.
Code:
paste(“Introduction”, “to”,” R”)
Output:
[1] Introduction to R
The default setting can be overridden using sep argument in paste()
Code:
paste(“Introduction”, “to”,” R”,”sep = “:”)
Output:
[1] Introduction:to:R
4. replicate() or rep() helps duplicate same string multiple times
Code:
replicate(3, “Introduction to R”)
rep(“Introduction to R”, 3)
Output:
