R语言 如何从给定的向量创建一个数据框架
在这篇文章中,我们将看到如何在R中从四个给定的向量创建一个数据帧。要在R中使用向量创建一个数据帧,我们首先必须有一系列包含数据的向量。data.frame()函数用于在R中从向量创建一个数据框。
语法 。
data.frame(vectors)
例1. 从给定的4个向量创建数据帧。
# creating a vector with some value
id = c(1, 2, 3)
# creating another vector with some value
name = c("karthik" , "nikhil" , "sravan")
# creating another vector with some value
branch = c("IT" , "CSE" , "IT")
# creating another vector with some value.
favourite_subject = c("SE" ,"DAA" , "OS")
# passing the vectors into data.frame() function
# as parameters
df1=data.frame(id, name, branch, favourite_subject)
# printing the data frame.
print(df1)
输出 。
例2 :
# creating a vector 1 with some values
faculty_id = c(247, 143, 01768)
# creating a vector 2 with some values
faculty_name=c("Subbarao", "praveen kumar", "sujatha")
# creating vector 3 with some values
designation=c("accociate professor", "assistant professor",
"accosiate professor")
# creating vector 4 with some data
salary = c(60000, 50000, 60000)
# passing the vectors to the data.frame() function
df3 = data.frame(faculty_id, faculty_name, designation,salary)
# printing the data frame created with 4 vectors
print(df3)
输出 。
