A simple package for tidy logging of everything you type into the R console.
You can install matahari from CRAN with:
install.packages("matahari")Or from GitHub with:
# install.packages("devtools")
devtools::install_github("jhudsl/matahari")library(matahari)
library(tidyverse)
library(knitr)
# Start logging your commands
dance_start(value = TRUE)
4 + 4
"wow!"
mean(1:10)
# Pause logging
dance_stop()
# Look at your log as a tibble
dance_tbl()
## # A tibble: 6 x 6
