Error in scan(file, what = "", sep = sep, quote = quote, nlines = 1, quiet = TRUE, : invalid 'sep' value: must be one byte

When I read the the file:
df<-read.csv("pseudo_facebook.tsv", sep = "/t")

The error displays. Please help me out
Error in scan(file, what = "", sep = sep, quote = quote, nlines = 1, quiet = TRUE, :
invalid 'sep' value: must be one byte

should be

sep = "\t"

The error message "invalid 'sep' value: must be one byte" is indicating that the separator value you are using in the read.csv() function is not a single byte. The sep parameter in the read.csv() function is used to specify the field separator character, and in your case, you are using the value "/t".

It looks like you might have intended to use the tab character as the field separator, however, the tab character is represented as "\t" in R, not "/t". To fix the error, you should change the separator value to "\t" like this:

df<-read.csv("pseudo_facebook.tsv", sep = "\t")

This should correctly read in the file with tab-separated values and prevent the error from occurring.
