R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot. ## Exercise 3

library(readxl)
## Warning: package 'readxl' was built under R version 4.4.3
car_sales <- read_excel(
  "C:/Users/Admin/Downloads/Assignment Act 65/Assignment Act 65/car_sales.xlsx"
)

car_sales <- data.frame(car_sales[, 1:13])
data <- na.omit(car_sales)
data[, -1] <- scale(data[, -1])
