How to install condformat:

Dependencies

If you want to use the PDF output you will need the xcolor LaTeX package. Either use the full texlive distribution, or install latex-xcolor on Debian and derivatives.

Package installation

  • From CRAN:

    install.packages("condformat")
    
  • To install the latest development version:

    devtools::install_github("zeehio/condformat")
    

Example

data(iris)
library(condformat)
condformat(iris[c(1:5,70:75, 120:125),]) %>%
  rule_fill_discrete(Species) %>%
  rule_fill_discrete(c(Sepal.Width, Sepal.Length),
                     expression = Sepal.Width > Sepal.Length - 2.25,
                     colours = c("TRUE" = "#7D00FF")) %>%
  rule_fill_gradient2(Petal.Length) %>%
  rule_text_bold(c(Sepal.Length, Species), Species == "versicolor") %>%
  rule_text_color(Sepal.Length,
                  expression = ifelse(Species == "setosa", "yellow", "")) %>%
  rule_fill_bar(Petal.Width, limits = c(0, NA)) %>%
  theme_grob(rows = NULL) %>%
  condformat2grob()

This example covers most of the condformat rules.
