R help - Jan 2018 - roxygen2 error - x$tag operator is invalid for atomic vectors

Hi,

  I am trying to create my first R package.
  I will later today put the files on Github.

  However I gets this error and I can't find any reason for it:

R> roxygen2::roxygenise()
First time using roxygen2. Upgrading automatically...
Error in x$tag : $ operator is invalid for atomic vectors
R>

  Any ideas?

Regards

This is an error message from R.
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).

HTH,
Eric

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

OK thanks.

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