fdth

fdth is an R package for frequency distribution tables, associated histograms, and polygons for numerical and categorical variables.

Key Features

• Frequency distribution tables from vectors, matrices, and data frames.
• Support for numerical (fdt) and categorical (fdt_cat) variables.
• Associated graphics, including histograms and frequency polygons.
• Summary measures from grouped data (for example, mean, median, and mode).
• Reporting support with xtable.

Installation

install.packages("fdth")

Install the development version from GitHub:

# install.packages("remotes")
remotes::install_github("jcfaria/fdth")

set.seed(123)
x <- rnorm(100, mean = 20, sd = 3)

ft <- fdt(x)
ft

plot(ft)
summary(ft)

# Most frequent value (mode) from grouped data
mfv(ft)
