For example, if you give the following R commands

  a <- 5
a$foo

This will generate the error message:
Error in a$foo : $ operator is invalid for atomic vectors

So you can search for the string 'x$tag' in your code (or possibly in the
package).



OK thanks.

Something else must be wrong because my package should only contain a
data.frame saved in .RData file


Immediately after the error, run traceback() to see where that code is 
being found.  The output might not mean much to you, but perhaps others 
here will spot the issue.


If that doesn't make the problem obvious, then post a link to your 
Github source and someone else will be able to try it.

Re: [R] roxygen2 error - x$tag operator is invalid for atomic vectors

[Ben Tupper]

Hi,

It's not really a roxygen thing but a subsetting thing.

> x = c(foo = 7, tag = 8)
> x$tag
Error in x$tag : $ operator is invalid for atomic vectors

For simple vectors you want ...

> x['tag']
tag 
  8 

... or ...

> x[['tag']]
[1] 8
