Always login to Rguroo through the Rguroo’s main website at https://www.rguroo.com: To sign-in, use the button on the top-right of the page. This ensures that you get the latest version of Rguroo, and the Rguroo application gets loaded into your browser correctly.
In addition to routine bug fixes, the following are major additions to the Version 1.8.13:
Changes have been made to definitions of ID/Label and Factor/Categorical variables. The following rules are applied to classify variables when data are initially uploaded to Rguroo:
Datasets associated with the following textbooks have been added to the Rguroo Dataset repository and are available within the Rguroo application:
While simple regression can be performed in Rguroo’s general Regression function, a separate simple regression function is added to provide an easy user interface to fit simple regression models. The following are what is included in the simple regression function:
A function called Summarization (Numerical) is added to provide univariate and multivariate summaries for numerical variables. Univariate summaries include various measures of center, spread, and shape. Moreover,you can compute any desired sample quantiles and truncated mean. The multivariate summary statistics include correlation and covariance matrix and Cronbach Alpha.
A function is added to create bubble plots. In addition to the usual Rguroo graph customizations, this function has the following capabilities:
A rounding option was added to the Dotplot function, which allows rounding of numbers in variables to a desired number of decimal places before a dotplot is created.
Two options of Text Size and Point Size were added to the Legend properties. This will allow for changing the size of the point characters and the texts in the legend independently.
Addition of a pin: The default behavior in Rguroo is that when the Preview icon is clicked, the dialog boxes close. A pin has been added to the dialog boxes, and when selected, the dialog boxes do not close when previewing results. This allows for quick changes of parameters and observing changes in the results.
Refresh button for toolboxes: You can login to Rguroo in two or more tabs in a browser. This is useful, for example, for showing Rguroo results side-by-side by pulling out a tab from the browser and showing contents of two tabs side by side. A refresh button is added to each of the toolboxes to synchronize what you save in one tab with that in another tab. Specifically, if you save an object in a toolbox in one tab, then to see that object in another tab, you can click on the refresh button.
