gglogger is an R package that logs the calls used to createggplot2 objects.

This can be useful for debugging, reproducibility, and understanding the sequence of operations used to build a plot.

Have you ever created a plot inggplot2 and then forgotten how you made it? Or wanted to reproduce a plot but couldn't remember the exact sequence of operations you used?gglogger can help!

Installation

You can install thegglogger package from source usingdevtools:

devtools::install_github("pwwang/gglogger")# orremotes::install_github("pwwang/gglogger")

Usage

To use thegglogger package, simply load it along withggplot2 and create your plots as usual. The package will automatically log the calls used to create the plots.

PreviousNow
library(ggplot2)p<- ggplot(mpg, aes(x=displ,y=hwy))+    geom_point()
library(ggplot2)# Just add gglogger after ggplot2library(gglogger)p<- ggplot(mpg, aes(x=displ,y=hwy))+    geom_point()# Print the logsprint(p$logs)## ggplot2::ggplot(mpg, aes(x = displ, y = hwy)) +##   geom_point()

Evaluate the code in logs to reproduce the plot:

p$logs$evaluate()

You can also attach the variables in an environment for evaluation:

env<- new.env()env$mpg<-mpgenv$mpg$hwy<-mpg$hwy/2p$logs$evaluate(env)

Registering a function from a ggplot2 extension

library(dplyr)library(gglogger)mtcars_radar<-mtcars %>%  as_tibble(rownames="group") %>%  mutate_at(vars(-group),scales::rescale) %>%  tail(4) %>%  select(1:10)ggradar<- register(ggradar::ggradar)p<- ggradar(mtcars_radar,legend.position="right")print(p$logs)# ggradar::ggradar(mtcars_radar, legend.position = "right")

Generating code to reproduce a plot

# p is a ggradar plot created in the previous examplecode<-p$logs$gen_code(setup='library(dplyr)library(ggradar)mtcars_radar <- mtcars %>%  as_tibble(rownames = "group") %>%  mutate_at(vars(-group), scales::rescale) %>%  tail(4) %>%  select(1:10)')cat(code)## library(dplyr)## library(ggradar)#### mtcars_radar <- mtcars %>%##   as_tibble(rownames = "group") %>%##   mutate_at(vars(-group), scales::rescale) %>%##   tail(4) %>%##   select(1:10)###### ggradar::ggradar(mtcars_radar, legend.position = "right")# eval(parse(text = code)) # to reproduce the plot

Limitations

gglogger cannot log the global settings used to create a plot, such astheme_set(). It can only log the calls used directly to create the plot itself. You may need to manually set these global settings when reproducing a plot, or prepare them using thesetup argument ingen_code().

If your data is piped toggplot function, you need to use|> instead of%>%, otherwise the data will be logged as..
