When a factor is converted into a numeric vector, the numeric codes corresponding to the factor levels will be returned.

The tidyverse package is an “umbrella-package” that installs tidyr , dplyr , and several other packages useful for data analysis, such as ggplot2 , tibble , etc.

See the forcats package for more tools for working with factors and their levels. Value. a vector of Date objects corresponding to x.. Compare to base R. These are drop in replacements for as.Date() and as.POSIXct(), with a few tweaks to make them work more intuitively.

The {across} function was just released in #dplyr 1.0.0. It's a NEW #tidyverse function that extends {group_by} and {summarize} for multiple column & functio

We are going to learn more about factor variables in Chapter 4, by using the {forcats} package. The Tidyverse packages provide a simple but powerful approach to data science which scales from the most basic analyses to massive data deployments. This course covers the entire life cycle of a data science project and presents specific tidy tools for each stage. You'll learn to work with data using tools from the tidyverse in R. By data, we mean any data with rows and columns that comes your way!

However, when loading the library: library (tidyverse). It throws the following issue: Error : object `as_factor' is not exported by 'namespace:forcats'.

This worked beautifully, can't believe I didn't have this in my code before! I pull from a oracle database that default assigns every column to either int or chr, and this add-on allows me to do quick QA to make sure all the appropriate rows were pulled and none were dropped.
