Exporting our linear regression results for publication is usually a cumbersome task, because there is a lot of important content in them (p-values, coefficients, other fit metrics) and R does not print particularly nice tables. 

One option is to export these numbers and create a new table in any text-editing software. But that takes a lot of effort, and it never looks that great.  

The sjPlot package can be used for creating publication-grade output values such as tables and plots, and it's not just restricted to operate with linear models, it can also work with a wide array of techniques (such as principal components and clustering).
