Beautiful HTML tables of linear models In this blog post I’d like to show some (old and) new features of the sjt.lm function from my sjPlot-package. These functions are currently only implemented in the development snapshot on GitHub. A package update is planned to be submitted soon to ... [Read more...]

My sjPlot package for data visualization has just been updated on CRAN. I’ve added some features to existing function, which I want to introduce here. Plotting linear models So far, plotting model assumptions of linear models or plotting slopes for each estimate of linear models were spread over several ... [Read more...]

In the last couple of weeks I have rewritten some core parts of my sjPlot-package and also revised the package- and online documentation. Most notably are the changes that affect theming and appearance of plots and figures. There’s a new function called sjp.setTheme which now sets theme-options for ... [Read more...]

My sjPlot-package was just updated on CRAN, introducing a new function called sjp.emm.int to plot estimated marginal means (least-squares means) of linear models with interaction terms. Or: plotting adjusted means of an ANCOVA. The idea to this function came up when we wanted to analyze the effect of ... [Read more...]

A new update of my sjPlot package was just released on CRAN. This release focused on improving existing functions and bug fixes again. Especially the table output functions (see my previous blog posts on table output functions here and here) improved a lot. Tables now have more and better possibilities ... [Read more...]

I just submitted my package update (version 1.3) to CRAN. The download is already available (currently source, binaries follow). While the last two updates included new functions for table outputs (see here and here for details on these functions), the current update only provides small helper functions as new functions. The ... [Read more...]

Finally, I managed to setup a GitHub repository. From now on, the latest developer snapshot of my sjPlot-package will be published right here: https://github.com/sjPlot/devel. Please post issues there, download the latest developer build for testing purposes or help developing the wiki-page with examples for package usage ... [Read more...]

First of all, I’d like to thank my readers for the lots of feedback on my last post on beautiful outputs in R. I tried to consider all suggestions, updated the existing table-output-functions and added some new ones, which will be described in this post. The updated package is ... [Read more...]

Inspired by these two postings, I thought about including a function in my package for simply creating scatter plots. In my package, there’s a function called sjp.scatter for creating scatter plots. To reproduce these examples, first load the package and then attach the sample data set: The simplest ... [Read more...]

About one year ago, I seriously started migrating from SPSS to R. Though I’m still using SPSS (because I have to in some situations), I’m quite comfortable and happy with R now and learnt a lot in the past months. But since SPSS is still very wide spread ... [Read more...]

I received a message asking me why I use so often numbers like 1e6 (exponential form) instead of writing down the whole numbers. I never thought on this before. However, I can assure that it's not because I'm lazy and don't like typing long numbers. In fact, thinking on this ... [Read more...]

It’s been a while since a user of my plotting-functions asked whether it would be possible to compare multiple (generalized) linear models in one graph (see comment). While it is already possible to compare multiple models as table output, I now managed to build a function that plots several (... [Read more...]

Few days ago I posted on doing a smart job on importing several data files alike from a directory. Today, I want to return to this topic, but stretching it a bit further by adding some complexity. I want to have a snapshot of the datasets even before starting work ... [Read more...]

Since version 0.8, my package for data visualization using ggplot has been released on the Comprehensive R Archive Network (CRAN), which means you can simply install the package with install.packages("sjPlot"). Last week, version 0.9 was released. Binaries are already available for OS X and Windows, and source code for Linux. ... [Read more...]

Today, I got a license of the new Stata/MP 13 (dual core), so I decided to make some succinct comparisons with R (Rstudio). Much more tests will come in the following weeks, but today I focused only on the basics: processing text files. Essentially, reading and writing raw datasets. The ... [Read more...]

I’d like to announce the release of version 0.7 of my R package for data visualization and give a small overview of this package (download and installation instructions can be found on the package page). What does this package do? In short, the functions in this package mostly do two ... [Read more...]

This weekend I had some time to deal with package building in R. After some struggling, I now managed to setup RStudio, Roxygen and MikTex properly so I can compile my collection of R-scripts into a package that even succeeds the package check. Downloads (package and manual) as well as ... [Read more...]
