Embedding subplots in ggplot2 graphics

I first learned about embedding many small subplots into a larger plot as a way to visualize large datasets with package ggsubplot. Embedding subplots is still possible in ggplot2 today with the annotation_custom() function. I demonstrate one approach to do this, making many subplots in a loop and then adding them to the larger plot.

Automating exploratory plots with ggplot2 and purrr

In this post I show an example of how to automate the process of making many exploratory plots in ggplot2 with multiple continuous response and explanatory variables. To loop through both x and y variables involves nested looping. In the latter section of the post I go over options for saving the resulting plots, either together in a single document, separately, or by creating combined plots prior to saving.

Time after time: calculating the autocorrelation function for uneven or grouped time series

Checking for autocorrelation must be done carefully when some observations are missing from a time series or the time series is measured for independent groups. I show an approach where I pad the dataset with NA via tidyr::complete() to fill in any missed sampling times and make sure groups are considered independent prior to calculating the autocorrelation function.

I currently work as a consulting statistician, advising natural and social science researchers on statistics, statistical programming, and study design. I create and teach R workshops for applied science graduate students who are just getting started in R, where my goal is to make their transition to a programming language as smooth as possible.
