Error: $ operator is invalid for atomic vectors

[chubbar1963]

When I run the dagitty function, I get the following error code:

Error: $ operator is invalid for atomic vectors

For example, the following is taken from the dagitty documentation::

g <- dagitty("dag{ 
  a -> b ;
  b -> c ;
  d -> c
 }")

Error: $ operator is invalid for atomic vectors

Traceback:

6. stop(e)
7. value[3L]
8. tryCatchOne(expr, names, parentenv, handlers[[1L]])
9. tryCatchList(expr, classes, parentenv, handlers)
10. tryCatch({ .jsassign(xv, as.character(x)) .jsassign(xv, .jsp("GraphParser.parseGuess(global.", xv, ").toString()")) ...
11. dagitty("dag{ \n a -> b ;\n b -> c ;\n d -> c\n }")

Any thoughts? Thanks!

Thank you for your message. I am afraid I cannot reproduce this problem, when I paste this code into R it works just fine. Can you please tell me more about your environment, e.g., what does "packageVersion('dagitty')" say and which version of R are you running?

Here you go. Thanks!

packageVersion('dagitty')

So you're using this on MinGW is that correct? I've never tried that TBH. I have a feeling that the V8 package might be the problem, it's a dependency and it's fairly complex. What do you get when you run "packageVersion('v8')" ?

[chubbar1963]

packageVersion('v8')

[1] ‘2.2’

As for MinGW, I don't really know. I thought I was running Windows 10

Here's what I get when I open System Information:

OS Name Microsoft Windows 10 Enterprise Version 10.0.17763 Build 17763

I believe this issue should be fixed now (see related issue #24). Closing it for now.

Im still having this issue, has there been a resolution?
