View data frame in r, within RStudio, the View() function in R can be used to call a spreadsheet-style data viewer.

The syntax for this function is as follows:

View(data)

When using this function, make sure to use a capital “V”.

The example below demonstrates how to utilize this syntax in practice.

## What Is the View() Function and How Do I view data frame in r?

To make a data frame in R with 500 rows and 2 columns, use the following code:

We can make this example reproducible while utilizing set.seed function

set.seed(454)

Let’s create a data frame using rnorm function.

data <- data.frame(x=rnorm(500),y=rnorm(500))

The View() function can then be used to open a spreadsheet-style data viewer in RStudio.

View(data)

In Rstudio, you’ll see a new tab that enables an interactive representation of the data frame we just created.

The size of the data frame may be seen at the bottom of the viewer: There are 500 entries (rows) and two columns.

## Using the View() Function to Sort Data

By clicking on one of the columns, we can easily sort the data set.

If we click on the column x header, for example, the data frame’s rows will be automatically sorted from least to largest depending on the values in column x.

If we click on the column x heading again, the data frame will be sorted from largest to smallest by column x.

## How to Use the View() Function to Filter Data

I can also filter the data frame fast by clicking the Filter button, then clicking one of the column names, and then entering a range of values.

For instance, we could filter the data frame to only display rows with x between 0 and 1:

Once we press enter, the data frame will automatically be filtered.

At the bottom of the screen, we can see that 173 rows have values in the x column between 0 and 1.

Note that we can also add a filter in the y column to filter by specific values in both x and y.
