| Title: | Track 'ggplot2' Calls |
| Version: | 0.1.7 |
| Description: | Provides a way to log 'ggplot' component calls, which can be useful for debugging and understanding how 'ggplot' objects are created. The logged calls can be printed, saved, and re-executed to reproduce the original 'ggplot' object. |

GGLog class
Description
The 'GGLog' class is used to store a single ggplot call.
Fields
codeA string to store the code of the ggplot call.
Methods
evaluate(envir = parent.frame())Evaluate the log.
@param envir The environment to evaluate the log in.
stringify()Stringify the log.
@return A string.
GGLogs class
Description
The 'GGLogs' class is used to store logs of ggplot calls. Each log is stored as a 'GGLog' object. The object can be accessed using the '$logs' field from a ggplot object.
Fields
logsA list to store the logs.
Methods
add(log)Add a log to the list.
@param log A GGLog object.
evaluate(envir = parent.frame())Evaluate all logs in the list.
@param envir The environment to evaluate the logs in.
gen_code(setup = "library(ggplot2)")Generate code for all logs in the list.
@param setup A string to setup the environment.
@return A string of code.
stringify()Stringify all logs in the list.
@return A string.
