strsplit(x, split = ";") error

[sciencificity]

Dear Danielle,

Thank you for this package. I am keen to use it to create neat little cards for code snippets for myself (and anyone else who stumbles on it) on my distill blog.

I downloaded the CRAN bs4cards and ran the example code of

galleries %>%
  cards(
    title = long_name,
    text = blurb,
    image = image_url,
    link = gallery_url
  )

in an RMarkdown document with the ffg. in the YAML header:

output:
  html_document:
    theme:
      version: 4

I get an error as follows however: "Error in strsplit(x, split = ";") : non-character argument Calls: ... dots_list -> card_class -> unique_tags -> unlist -> strsplit"

I tried adding tags as follows and I experience the same error.

galleries %>%
  cards(
    title = long_name,
    text = blurb,
    image = image_url,
    link = gallery_url,
    tags = paste0("All;", "R")
  )

I also copied the unique_tags and card_class functions into my R code, and ran it on card_class(paste0("All;", "R")) which worked 100%.

The only package I do not have is methods which is in the imports section. I am unsure if that is the issue but I cannot find a CRAN version of it. I tried to do a reprex but the error experienced is that it could not find function '%>%' which is not the problem I am experiencing (I also purposely loaded magrittr, which made no difference). I am on version 3.6.3 of R but the depends is > 2.10, so I am hoping it is not that. I suspect I am doing something stupid or missing something essential and I would appreciate the help.

Thank you!

Hi!

Thanks for trying out the package. That looks suspiciously like a bug 🐛 in the function that parses the tag, so I think the problem is at my end. I doubt it's anything to do with your R environment (methods is one of the base packages, so you're all set there). Almost certainly the issue is that I didn't write very robust code for handling the inputs there. I'll aim to take a look at this soon, and thanks so much for reporting the problem!

Best,
Danielle

I think the root of this issue comes down to stringsAsFactors strikes again (for those of us still working with R <= 3.6.3). You should be able to get around the problem right now using

options(stringsAsFactors = FALSE)

Ag, that makes sense. Thanks Garrick. I guess stringsAsFactors really is = . I got a new laptop and upgraded to version 4.1.1 and the problem does not exist there.
Thanks so much for the package Danielle, it is lovely!

Brilliant, thanks @gadenbuie! I'll merge #38 now, hopefully fixing this! Thanks for opening the issue @sciencificity
