rStudio Does Not Show Date on Chart Correctly

Here is my script so you can copy paste.

(Dataset contains .csv file containing Dates + Daily Closing Prices of Nasdaq 100)

The script works beautifully except it refuses to show dates on x axis (see screenshot). Please help, here is the script I've been working on:

library(tidyverse)

library(tseries)

library(forecast)

nasdaq <- read_csv("Desktop/r data/^NDX.csv")

View(nasdaq)

as.Date(df$Date, "%d%m%y")

pClose <- ts(nasdaq[, 'Close'], start =c(2020,5), frequency = 52)

fit_ARIMA <- auto.arima(pClose, seasonal = TRUE)

print(summary(fit_ARIMA))

fcast <- forecast(fit_ARIMA, h = 5)

autoplot

plot(fcast)

print(summary(fcast))
