I was trying to use these libraries:
library(kernlab)
library(kknn)
library(tidyverse)
library(ggplot2)
library(dplyr)
library(magrittr)
library(caret)
library(e1071)
library(class)
They worked before.
After I clear the environment, I can no longer load the libraries.
Here is the error message I have:
install.packages("kernlab")
WARNING: Rtools is required to build R packages but is not currently
installed. Please download and install the appropriate version of
Rtools before proceeding:

Any help is appreciated.
I downloaded the RStudio and Rtools again. It still didn't install the packages properly.
