[R] Retrieving data from survey in R Studio

[Bob Rudis]

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()`.
