I see that is_fraud is coded as 0 or 1, and the mean of this variable is 0.00525. The number of fraudulent transactions is very low, and we should use treatments for imbalanced classes when we get to the fitting/ modeling stage. Webb8 dec. 2024 · tibble. One major aspect of the tidyverse is formatting tables as tibble instead of data.frame.A tibble “is a modern reimagining of the data.frame, keeping what time has proven to be effective, and throwing out what is not.” It is super simple to convert a data.frame into a tibble, but you must have the tidyverse R package {tibble} installed …

These include select, filter, mutate ... Webb14 sep. 2024 · The approach I have been taking is: Introduce individual packages first to complete new useRs (and this usually means for a while it's only a few of the packages within tidyverse that they'll be using, most likely only dplyr and ggplot2 ), I introduce the individual packages. We specifically load them and not tidyverse.
