What is this error?

What does this error mean and how do I fix it?
Error: Couldn't find '_rels/.rels' in '/Users/..//Desktop/....csv'

Please show the code that produced that error. Try to reduce the code to the smallest number of lines that still produce the error.

It means either that the file doesn't exist at all or it doesn't exist where it's being looked for.

The best way to minimize this is to keep your data files in or under your working directory and use the {here} package.

What I do with a new RStudio project is to create a directory data where I put all raw data. Then to read it in

d <- fread(here("data/mydata.csv")

for example.Preformatted text
