I am running the following code...
#Create a list of all the files
file.list <- list.files(path=\"~/R/natural-language-processing/class-notes\", pattern=\".cs
read.csv is looking for the file names in your working directory. By changing your working directory to "C:/Users/Bob/Documents/R/natural-language-processing/class-notes", your code should work just fine.
Code:
setwd("C:/Users/Bob/Documents/R/natural-language-processing/class-notes")
Then re-run your code.
