"Unrecognized escape in character string" while attempting to read a CSV file

I am trying to import a .csv file, so that I can follow along with this video: R ggplot2 Graphics Histograms.

I installed all proper packages including ggplot and related packages. The first instruction in the video says to type afl.df=read.csv("afl_2003_2007.csv")

So, I downloaded afl_2003_2007.csv file, and I tried all the below, which was basically putting the file in different directories (shared drive, then C drive, etc.). I also tried using setwd, but no luck.

I am using R in windows.

Here's what I tried, and the errors I got:

> afl.df=read.csv("afl_2003_2007.csv")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :

Use / instead of \ in your path:

afl.df=read.csv("C:/Users/lopez235/Local-NOTBackedUp/R Files Local/afl_2003_2007.csv")
