Concatenación por elementos del vector de string en R

La concatenación de elementos de dos vectores significa tomar simultáneamente valores de dos vectores y unirlos o concatenarlos en uno. Para esto, la función paste() se usa en el lenguaje de programación R.

Sintaxis:

pegar(vector1,vector2,….,vectorn)

Donde, los vectores son las entradas para pegar la función

Ejemplo 1:

# 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))

Producción:

[1] “sravan kumar” “bobby kumari” “mohan pavan” “sai kumar”

Podemos combinar n elementos vectoriales a la vez

Ejemplo: 2 

# 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))

Producción:

[1] “sravan kumar H” “bobby kumari B” “mohan pavan G” “sai kumar M” 

Si no necesitamos dejar un espacio entre dos strings concatenadas, use la función paste0() .

Sintaxis:

pegar0(vector1,vector2,…,vectorn)

Ejemplo:

# 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))

Producción:

[1] “sravankumar” “bobbykumari” “mohanpavan” “saikumar”

[1] “sravankumarH” “bobbykumariB” “mohanpavanG” “saikumarM”
