In this article, we will discuss how to convert the matrix into DataFrame, or we can also say that we will discuss how to create a DataFrame from a matrix in R Programming Language.
A matrix can be converted to a dataframe by using a function called as.data.frame(). It will take each column from the matrix and convert it to each column in the dataframe.
Syntax:
as.data.frame(matrix_data)
Where, matrix_data is the input matrix.
Example 1:
R
# create the matrix with 4 rows # with numeric elements matrix_data=matrix(c(1,2,3,4,5,6,7,8),nrow=4)
# display the data print(matrix_data)
# convert the matrix into dataframe dataframe_data=as.data.frame(matrix_data)
# print dataframe data print(dataframe_data)
|
Output:
Example 2:
R
# create the matrix with 8 rows # with numeric elements matrix_data=matrix(c(1,2,3,4,5,6,7,8,11:18),nrow=8)
# display the data print(matrix_data)
# convert the matrix into dataframe dataframe_data=as.data.frame(matrix_data)
# print dataframe data print(dataframe_data)
|
Output:
Example 3:
R
# create the matrix with 8 rows # with different elements matrix_data=matrix(c(
"bobby","pinkey","rohith","gnanesh",5.3,6.6,7,8,11:18),nrow=8)
# display the data print(matrix_data)
# convert the matrix into dataframe dataframe_data=as.data.frame(matrix_data)
# print dataframe data print(dataframe_data)
|
Output:
