R Set Dimensions of Empty Data Frame – n Rows & m Columns (Example Code)

In this R tutorial you’ll learn how to construct a data frame having n rows and m columns.

Example: Create Empty Data Frame with Certain Dimensions

my_df <- as.data.frame(matrix(0, nrow = 8, ncol = 5))  # Constructing empty data frame
my_df                                                  # Showing empty data in RStudio console
#   V1 V2 V3 V4 V5
# 1  0  0  0  0  0
# 2  0  0  0  0  0
# 3  0  0  0  0  0
# 4  0  0  0  0  0

# 7  0  0  0  0  0
# 8  0  0  0  0  0
