Here we are explaining how to write an R program to create an empty data frame. Here we are using a built-in function data.frame() for creating it. A data frame is used for storing data tables which has a list of vectors with equal length. The data frames are created by function data.frame(), which has tightly coupled collections of variables.
Below are the steps used in the R program to create an empty data frame. In this R program, we directly give the values to the built-in function. And print the function result. Here we used the variable Df is used as a data frame. The data frame consists of different data types which are integer, Doubles, Characters, Logical, Factors, StringsAs Factors.
STEP 1: Consider variable Df as a data frame.
STEP 2: Call data.frame() with different data types
STEP 3: Assign Df with function result
STEP 4: print the result of the function
Df = data.frame(Ints=integer(),
Doubles=double(),
Characters=character(),
Logicals=logical(),
Factors=factor(),
stringsAsFactors=FALSE)
print("Structure of the empty dataframe:")
print(str(Df))
[1] "Structure of the empty dataframe:" 'data.frame': 0 obs. of 5 variables: $ Ints : int $ Doubles : num $ Characters: chr $ Logicals : logi $ Factors : Factor w/ 0 levels: NULL
