Ulrik: you can absolutely read from a URL in read.csv() with that syntax. The error `## Error in attach(survey): object 'survey' not found` suggests that the OP mis-typed something in the `survey` name in the assignment from `read.csv()`.
However, the OP has quite a bit more to be concerned about than the missing variable in the environment if their stats program is encouraging both no spaces between operators and the use of `attach()`.
