# 
## Overview
The **`nrow()` and `ncol()` functions** find the number of rows and columns of a given data frame respectively.
## Syntax
```r
nrow(dataframe)
ncol(dataframe)
```
## Parameter value
Both the `nrow()` and `ncol()` functions take the same parameter value. This value represents the data frame object whose number of rows and columns is to be determined.

## Return value
The `nrow()` function returns the number of rows present in a given data frame, while the `ncol()` function returns the number of columns present in a data frame.

## Code example


# creating a data frame
My_Data_Frame <- data.frame (
  Height = c("Tall", "Average", "short"),
  Body_structure = c("Meso", "Endo", "Ecto"),
  Age = c(35, 30, 45)
)

# printing the data frame
print(My_Data_Frame)

# number of rows
nrow(My_Data_Frame)

# number of columns
ncol(My_Data_Frame)

## Code explanation
* **Line 2**: We create a data frame variable, `My_Data_Frame`, using the `data.frame()` function. The data frame contains three columns.
* **Line 9**: We print the data frame `My_Data_Frame`.
* **Line 12**: We check for the number of rows in the data frame, `My_Data_Frame`, using the `nrow()` function.
* **Line 15**: We check for the number of columns in the data frame, `My_Data_Frame`, using the `ncol()` function.

The code output tells us that the `My_Data_Frame` data frame contains `3` rows and `3` columns.


What are the ncol() and nrow() functions for a data frame in R?

nrow() returns the number of rows and ncol() returns the number of columns in a data frame in R.
