Graphs

This site is the home, a personal package, and a vehicle for graphs made with R. It installs the source code of illustrations and other graphs that I made and provides convenient functions to make graphs with ggplot2 (e.g. slope plots.)

Installation

You can install Graphs from GitHub with:

# install.packages("devtools")
devtools::install_github("edgar-treischl/Graphs")

Example

Without input, the plotgraph() function returns all available graphs.

library(Graphs)
plotgraph()
#> Error in plotgraph(): Please run `plotgraph()` with a valid argument.
#> Valid examples are:
#> anscombe_quartet.R
#> boxplot_illustration.R
#> boxplot_pitfalls.R
#> data_joins.R
#> datasaurus.R
#> gapminder.R
#> pacman.R
#> simpson.R
#> ucb_admission.R

The plotgraph() function just picks the installed source code and returns the graphs. For example, the datasaurus plot.

## basic example code
plotgraph("datasaurus.R")

And the package gives access to convenient functions to make ggplot2 graphs with less effort. For example, ggslope() returns a slope chart.

df <- tribble(
 ~times, ~country,  ~gdp, ~inc,

 "1990",   "B",  12.3, FALSE,
 "2000",   "B",  4.6, FALSE
 )

ggslope(df,
         times = times,
         outcome = gdp,
         group = country)+
  theme_minimal()
