How to select multiple DataFrame columns by name in R ?

In this article, we will discuss how to select multiple columns from a DataFrame by name in R Programming Language. To get multiple columns we will use the list data structure. By using a list we can pass the dataframe columns separated with a comma. Then, we can get list by using list() function

Syntax:

list(dataframe_name$column1,dataframe_name$column2,.,dataframe_name$column n)

Example1:

R

# create a vector with student id
vector1=c(7058,7059,7075,7076)

# create a vector with student name
vector2=c("Sravan kumar","Jyothika",
          "Deepika","Kyathi")

# create a vector with student address
vector3=c("ponnur","tenali","repalle",
          "ponnur")

# pass these vectors to the dataframe
dataframe1=data.frame(id=vector1,names=vector2,
                      address=vector3)

print(dataframe1)

# select multiple columns from the
# dataframe1 using list datastructure
a=list(dataframe1$id,dataframe1$names,dataframe1$address)

print(a)

Output:

Example 2:

R

# create a vector with student id
vector1=c(7058,7059,7075,7076)

# create a vector with student name
vector2=c("Sravan kumar","Jyothika",
          "Deepika","Kyathi")

# create a vector with student address
vector3=c("ponnur","tenali","repalle","ponnur")

# pass these vectors to the dataframe
dataframe1=data.frame(id=vector1,names=vector2,
                      address=vector3)

print(dataframe1)

# select multiple columns from the
# dataframe1 using list datastructure
a=list(dataframe1$id,dataframe1$names)

print(a)

Output:
