Best answer

You can use **nrow()** and **ncol()** functions to find the number of rows and columns in a dataframe respectively.

You can also use the dim() function to get the dimension of the dataframe.

Here is an example:

> x=c(1,2,3,4,5,6,7)

> y=c(11,12,13,14,15,16,17)

> df = data.frame(x=x, y=y)

> df

x y

1 1 11

2 2 12

3 3 13

4 4 14

5 5 15

6 6 16

7 7 17> nrow(df)

[1] 7> ncol(df)

[1] 2

Using the **dim()** function:

> x=c(1,2,3,4,5,6,7)

> y=c(11,12,13,14,15,16,17)

> df = data.frame(x=x, y=y)

> dim(df)

[1] 7 2
