rjutils : Enhanced R functions

Welcome to rjutils, a collection of enhanced functions for R, notable :

• A custom ggplot2 theme called jtheme
• Plotting function helpers for ggplot2
• Text modification function

Installation

rjutils use the Source Sans Pro, which is an open source font from Google. It needs to be installed on your system and in R. It is located in the assets/ folder of the package. You will need the packages extrafont and Rttf2pt1 in order to get the Source Sans Pro into R properly before you can use rjutils.

1. Install ggplot2 and extrafont packages :

install.packages("ggplot2")
install.packages("extrafont")

2. Install Rttf2 using the remotes package :

install.packages("remotes")
library(remotes)
remotes::install_version("Rttf2pt1", version = "1.3.8")

3. Import the Source Sans Pro font into R :

extrafont::font_import(path = "assets/")

4. You can now install rjutils directly from GitHub :

install.packages(
    ?????????
)

5. You can start using rjutils.

library(rjutils)

Bugfixes

To add

• Add function to avoid decimal on x-axis
• Move all others functions to jtheme or jutils prior to article 3

To fix :

• Test error message for save_plot()
• Fix argument "bottom" in jarrange() that will put the label below the legend.

Work in progres :

• Remove warnings() when using jarrange : Connot reproduce
• 50: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), ... : largeur de police inconnue pour le caractère 0x20 : Cannot reproduce

Done :

• Add facet title and size to params of jtheme(facet_size = 10L, facet_face = "bold")
• Added fast histogram plot_hist(x, main, fill) in plots.R
• Added fast scatter plot plot_scatter(x, y, main, col) in plots.R
• Added empty plot in plot_void() in plots.R
• Added another palette of colors (rainbow) in pal_rbow
• Renamed colors palette to pal_rdbu and rearrange order of colors
• Implemented rotate_x_lab = 90, 45 and 30 instead of TRUE
• Removed w and h for save_plot and save_ggplot. Replace by size = c(w, h)
• Implemented axes = FALSE to remove axes for maps. To be used with labs(x = NULL, y = NULL)
• Plot named color of palette when using plot_pal. Possibility to rotate names to 90°. Now accept list and vector.
• Migrated create_lagged_var from data_weather to this package.
• Migrated interpolate_na from data_weather to this package.
• Migrated xpaste0 from results to this package.
• Migrated narmfrom results to this packages.
• Combined all small low-level function in helpers.R
• Got rid of .Rplots.pdf at the root of all Rproject
• Implemented option title_hjust = 0.5 for jtheme()
• Added the operator %nin% which is equivalent to !(x %in% y)
• Added the function render_md_github() which allows conversion of .md to .html with Github format
• Added the function plot_cor_mat() to plot a correlation matrix as a ggplot2 object with jtheme.
