"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") : cannot open file 'afl_2003_2007.csv': No such file or directory > afl.df=read.csv("\\the-lab.llnl.gov\llnlusers1\lopez235\Data\Documents\Dashboards,HRBI, Visulizations and Analytics\Math and Statistics and Predictive Modeling1\R Programming\afl_2003_2007.csv") Error: '\l' is an unrecognized escape in character string starting "\\the-lab.llnl.gov\l" > afl.df=read.csv("C:\Users\lopez235\Local-NOTBackedUp\R Files Local\afl_2003_2007.csv") Error: '\U' used without hex digits in character string starting "C:\U" > setwd("\\the-lab.llnl.gov\llnlusers1\lopez235\Data\Documents\Dashboards,HRBI, Visulizations and Analytics\Math and Statistics and Predictive Modeling1\R Programming\afl_2003_2007.csv") Error: '\l' is an unrecognized escape in character string starting "\\the-lab.llnl.gov\l" > setwd("\\the-lab.llnl.gov\llnlusers1\lopez235\Data\Documents\Dashboards,HRBI, Visulizations and Analytics\Math and Statistics and Predictive Modeling1\R Programming") Error: '\l' is an unrecognized escape in character string starting "\\the-lab.llnl.gov\l" > setwd("C:\Users\lopez235\Local-NOTBackedUp\R Files Local") Error: '\U' used without hex digits in character string starting "C:\U" ```
