ggedit

ggplot2 has become the standard of plotting in R for many users. New users, however, may find the learning curve steep at first, and more experienced users may find it challenging to keep track of all the options (especially in the theme!).

ggedit is a package that helps users bridge the gap between making a plot and getting all of those pesky plot aesthetics just right, all while keeping everything portable for further research and collaboration.

ggedit is powered by a Shiny gadget where the user inputs a ggplot plot object or a list of ggplot objects. You can run ggedit directly from the console or from the Addin menu within RStudio.

Installation

CRAN

install.packages('ggedit')

For a quick example, run the following:

library('ggedit')
library(ggplot2)
p <- ggplot(mtcars, aes(x = hp, y = wt)) + geom_point() + geom_smooth()
p2 <- ggedit(p)
names(p2) # will show you which objects are available.
plot(p2) # shows the updated plot (it is available in the first element of p2)

DEV

devtools::install_github("metrumresearchgroup/ggedit")

DEV updates ggedit_0.2.1

• print.ggedit: S3 method to print directly from the output object to the console the script to reproduce changes on the original plot object

    print(obj)
    
    point
    geom_point(mapping=aes(colour=Species),alpha=0.5,size=3)+
    scale_colour_manual(values=c('#9E4A3F','#008B45','#6495ED'))
    
    pointWrap
    geom_point(mapping=aes(colour=Species),size=6)+
    theme(panel.background=element_rect(fill='white'))
    
    boxplotWrap
    geom_boxplot()
    
    pointLine
    geom_point(mapping=aes(shape=Species,colour=Petal.Width),size=6)+geom_line(linetype=2)

• compare: compare two theme objects and return script or new theme object with only the differences between the two

    compare(theme_bw(),theme_get())
    
    theme(legend.key=element_rect(fill='white'),
          panel.background=element_rect(fill='white'),
          panel.grid.major=element_line(colour='grey92'),
          panel.grid.minor=element_line(colour='grey92'),
          strip.background=element_rect(colour='grey20')
          )

• call to ggedit is now ggedit(p.in,...), where the following arguments can be passed in to the ellipses

  • viewer shiny viewer options. It can be either paneViewer (default with minHeight=1000), dialogViewer, browserViewer

  • verbose logical to control if the output includes script for layers and themes calls for parsing to create objects (default, verbose=TRUE)

  • showDefaults toggle to control if the verbose output shows all the input arguments passed to the proto object (if verbose==FALSE then ignored)

  • width,height dimensions of the renderPlot where the active plot is displayed

Limitations

• layers
  • non colour aesthetics of numeric inputs are not currently supported, e.g.: iris%>%ggplot(aes(x=Sepal.Length,y=Sepal.Width))+geom_point()+geom_text(aes(label=Species,size=Sepal.Length))
  • geom_text: family is not currently open to change
• theme
  • margin,arrow are not currently available to edit
