This quick guide provides step-by-step Rguroo instructions and examples for common statistical analyses and graphs. Throughout, there are clickable video icons linked to the Rguroo Video Tutorials Library for the presented topic. Additionally, you can get more technical details for most topics by clicking on the User’s Guide icon .
Most examples use data available in the Rguroo dataset repositories, and therefore you can reproduce the examples by importing the datasets from the Rguroo dataset repositories. See the Rguroo’s Dataset Repository section to learn how to import a dataset from the repository to your Rguroo account.
You can use Rguroo’s dataset editor to perform the following tasks:
The following are the main components of the dataset editor:
Search and Replace icon, used for searching and replacing text.
Variable and Row Management icon, used for performing tasks such as renaming variables, adding variables, managing variable types, relabeling and reordering levels of Factor (categorical) variables, and adding rows and variables.
Summary Data icon, used for getting a quick data summary for the dataset that is being viewed.
Deleted Rows icon, used for retaining deleted rows and restoring them.
Variable Context Menu icon appears when your cursor is placed over a variable name on the header. It provides options for for pinning and auto-sizing columns and renaming the corresponding variable.
Right-click on a cell provides options for copying and cutting selected cells, and pasting then (using Cntrl+V). It moreover, allows for adding and deleting rows, and exporting data to a CSV or Excel file.
Quick Search textbox, used for forward and backward text search.
Quick Filter textbox, used for filtering rows that contain a specific text within the entire dataset.
Save As textbox, used for saving datasets.
Column Sidebar Menu, located on the right-hand side of the editor window, includes a list of all the variables in the dataset. It is used for reordering, removing, or restoring removed variables (columns).
Filter Sidebar Menu, located on the right-hand side of the editor window, includes a list of all the variables in the dataset. It is used for filtering specific values within each variable.
You can create and save a new dataset using the following instructions:
Open the Data toolbox located on the left-hand side of the Rguroo application window.
Click on the Data Import dropdown, , and select the Create New Dataset option. The Create New Dataset dialog opens. Specify the number of rows and columns for your new dataset.
The default variable names will be Var1, Var2, etc. Refer to the Section Changing Variable Names to see how to change the variable names.
Enter your data. See the Notes below on how to navigate between cells when entering data.
Enter a name for your dataset in the Save As textbox on the top, and click the button to save your dataset.
By default, the number of rows is set to 500 and the number of columns is set to 30. You have the option to modify these values. If you are uncertain about the specific number of rows and columns you will need,select a larger grid by specifying a large number of rows and columns. This ensures that you have enough space to accommodate your data. After saving the dataset, when you reopen it, the grid will automatically adjust to match the actual number of rows and columns used by your data.
You can add additional rows and columns, if needed (see section 2.3).
When you login, Rguroo’s dataset editor opens in a tab without any data. You can close the dataset editor tab at anytime.
To enter values into cells and navigate through them using the keyboard, follow these instructions:
To edit an existing dataset use the following instructions:
Open the Data toolbox located on the left-hand side of the Rguroo application window to see the names of the existing datasets.
Use one of the following three options to edit a selected dataset:
Use the dataset editor features to modify your dataset. See Notes in the Section Creating a new dataset on how to enter data and navigate between cells.
Click the button to save your changes.
Note: Categorical variables, and specifically Nominal and Ordinal variables, are referred to as Factors in Rguroo.
In the dataset editor, the name of each variable is displayed on the column header. Default variable names are Var1, Var2, etc. You have two options, shown below, for changing variable names. The first option is useful when you need to change the names of multiple variables at the same time, while the second option is useful when you want to change the name of a single variable quickly.
Click on the Variable and Row Management icon . This will open the Variable and Row Management dialog.
From the list of variables displayed, select the variable that you want to rename.
Locate the Name textbox within the dialog, and type your desired new variable name in the textbox.
Press the Enter key on your keyboard. The new variable name will now appear in the header, replacing the old name.
Note: Variable names cannot contain spaces. Make sure to avoid using spaces when entering the new variable name.
Move your cursor over the variable name on the header. You will see the Variable Context Menu icon .
Click on the icon to open the variable context menu (shown on the left panel in the figure below).
From the menu select the option Rename. This will bring up the Rename Variable dialog box (shown on the right panel in the figure below).
In the dialog box, type in the new name for your variable, and press enter. The new name will now appear on the header. Note that variable names cannot have spaces.
Use the following instructions to add new variables to your dataset:
Click on the Variable and Row management icon to open its dialog.
Select the Add Variables option. The dialog shown in the figure below shows.
Type in the number of variables that you want to add in the No. of Variables textbox.
Select one of the Beginning or End options to place the variables.
Type a prefix for the name of the variables in the Name textbox. If you are adding a single variable, simply type in the name of the variable. (See notes below regarding variable names when adding multiple variables).
Click on the button.
When adding variables to your dataset, there are two possible scenarios to consider for naming the variables:
Adding a Single Variable:
Adding Multiple Variables:
To change the location of variables in your dataset, you have two options:
Click and hold:
Columns Side Bar:
There are two options for adding rows to a dataset. The first option, described below, is useful for adding multiple rows simultaneously, while the second option is useful when you want to add one row at a time.
Click on the icon to open the Variable and Row Management dialog.
Select the Add Rows option. The dialog box shown in the figure below will appear.
Type in the number of rows that you want to add in the # of Rows textbox.
Select from one of the options Beginning, End, or Below Selected Row to indicate where you want the rows to be added.
Click on the button.
