Do you use R or Python to preprocess datasets for analyses? smallsets
is an R package (https://CRAN.R-project.org/package=smallsets) that
transforms the preprocessing code in your R, R Markdown, Python, or
Jupyter Notebook file into a Smallset Timeline. A Smallset Timeline is a
static, compact visualisation composed of small data snapshots of
different preprocessing steps. A full description of the Smallset
Timeline can be found in the paper Smallset Timelines: A Visual
Representation of Data Preprocessing
Decisions in the proceedings
of ACM FAccT ’22.
The smallsets
user guide is available
here
and in the package in vignette("smallsets")
. If you have questions or
would like help building a Smallset Timeline, please email
Lydia.

Run this snippet of code to build your first Smallset Timeline! It’s based on the synthetic dataset s_data, with 100 observations and eight variables (C1-C8), and the preprocessing script s_data_preprocess.R, discussed in the following section.
library(smallsets)
set.seed(145)
Smallset_Timeline(data = s_data,
code = system.file("s_data_preprocess.R", package = "smallsets"))
The Smallset Timeline above is based on the R preprocessing script
below, s_data_preprocess.R. Structured comments were added to it,
informing smallsets
what to do.
# smallsets snap s_data caption[Remove rows where C2 is FALSE.]caption
s_data <- s_data[s_data$C2 == TRUE, ]
# smallsets snap +2 s_data caption[Replace missing values in C6 and C8 with
# column means. Drop C7 because there are too many missing values.]caption
s_data$C6[is.na(s_data$C6)] <- mean(s_data$C6, na.rm = TRUE)
s_data$C8[is.na(s_data$C8)] <- mean(s_data$C8, na.rm = TRUE)
s_data$C7 <- NULL
# smallsets snap +1 s_data caption[Create a new column, C9, by summing C3 and
# C4.]caption
s_data$C9 <- s_data$C3 + s_data$C4
