Error: 'R' is an unrecognized escape in character string starting "C:R"

Question

I am running Windows XP Pro and R Version 2.15.1 R is installed in the following folder:

C:Program FilesRR-2.15.1

I am trying to create a function that reads in a .csv file like so:

xxx <- function(id, directory, summarize = FALSE) {
    data <- read.table('C:xxxclassesR_Progspecdatadata.csv')
    head(data)
}

I get the error

Error: 'R' is an unrecognized escape in character string starting "C:R"

Is there a problem with my directory structure / folder naming conventions?

Answer 1

You have to escape the since it is itself an escape character.

read.table('C:\xxx\classes\R_Prog\specdata\data.csv') head(data) }
