Installation

You can install the released version of tabit from CRAN with:

install.packages("tabit")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("petermeissner/tabit")

Example

# load package
library(tabit)

simple vectors

# simple tabulation
tabit(mtcars$cyl)

simple data.frames

# can we do this with data.frames
tabit(mtcars[, c("cyl", "am")])

simple tibbles

# what about this tibble thing?
suppressPackageStartupMessages({
  library(dplyr)
})
mtcars %>% 
  select(cyl, am) %>% 
  tabit()

grouped tibbles

# ... and grouped tibbles?
mtcars %>% 
  group_by(cyl, am) %>% 
  tabit()

too much magic?

# use tabit_1() for vector usage
tabit_1(letters[1:4])

# use tabit_x for data.frames and tibbles
tabit_x(mtcars[, c("cyl", "am")])
