Mastering gt_summary: Filtering, Custom Formatting, and Precision Control for Concise Data Summaries in R
gt_summary Filtering: Subset of Data, Custom Formatting, and Precisions Introduction The gt_summary package from ggplot2 is a powerful tool for summarizing data in R. It allows users to create concise summaries of their data, including means, medians, counts, and more. However, when working with large datasets or datasets that require specific formatting, it can be challenging to achieve the desired output. In this article, we will explore how to use gt_summary to filter a subset of data, apply custom formatting to numbers under 10, and remove automatic precisions.

Understanding the Implications of Non-Equal Slopes in Regression Analysis: A Case for Further Investigation.
Based on the code output, the null hypothesis that the slopes are equal cannot be rejected. The estimated intercept (-2120.98) and the coefficient of log(VE) (914.32) indicate a positive relationship between absVO2 and log(VE), which is consistent with your initial assumption. However, the interaction term groupHealthy:log(VE) (60.52) suggests that there may be some variation in the slope between groups Healthy and CAD. While this coefficient is not significant (p-value = 0.
