library caret Loading required package: lattice Loading required package: ggplot2 R

Question

library(caret)
Loading required package: lattice
Loading required package: ggplot2

I already installed lattice, ggplot2, since I used install.packages("caret", dependencies = TRUE) . Nothing is working. Help!

Answer 1

A package loading other required packages is normal behavior in R. To confirm that caret has been loaded, one can run the following code.

library(caret)

loaded_packages  <- library()$results[,1]

# confirm caret is loaded
"caret" %in% tolower(loaded_packages)

...and the output:

> # confirm caret is loaded
> "caret" %in% tolower(loaded_packages)
[1] TRUE
