Element-wise concatenation of string vector in R
Element wise concatenation of two vectors means concurrently taking values from two vectors and joining or concatenating them into one. For this paste() function is used in the R programming language.
Syntax:
paste(vector1,vector2,….,vectorn)
Where, vectors are the inputs to paste function
Example 1:
R
# create a vector named as first_names first_names=c("sravan","bobby","mohan","sai") # create a vector named as middle_names middle_names=c("kumar","kumari","pavan","kumar") # apply paste function print(paste(first_names,middle_names)) |
Output:
[1] “sravan kumar” “bobby kumari” “mohan pavan” “sai kumar”
We can combine n vector elements at a time
Example: 2
R
# create a vector named as first_names first_names=c("sravan","bobby","mohan","sai") # create a vector named as middle_names middle_names=c("kumar","kumari","pavan","kumar") # create a vector named as middle_names last_names=c("H","B","G","M") # apply paste function print(paste(first_names,middle_names,last_names)) |
Output:
[1] “sravan kumar H” “bobby kumari B” “mohan pavan G” “sai kumar M”
If we do not need to give a gap between two concatenated strings use paste0() function.
Syntax:
paste0(vector1,vector2,…,vectorn)
Example:
R
# create a vector named as first_names first_names=c("sravan","bobby","mohan","sai") # create a vector named as middle_names middle_names=c("kumar","kumari","pavan","kumar") # create a vector named as middle_names last_names=c("H","B","G","M") # apply paste0 function fro combining first and middlename print(paste0(first_names,middle_names)) # apply paste0 function fro combining first middlename and last names print(paste0(first_names,middle_names,last_names)) |
Output:
[1] “sravankumar” “bobbykumari” “mohanpavan” “saikumar”
[1] “sravankumarH” “bobbykumariB” “mohanpavanG” “saikumarM”
