Set manually `stringsAsFactors = FALSE`

From Tom at SG via email:

I tried running through your example: https://co-analysis.github.io/a11ytables/articles/a11ytables.html

We are only using R 3.6.3... At R versions >= 4.x.x data.frame stringsAsFactors argument is FALSE by default (I think), but this is TRUE at R 3.6.3.

This means the data frame “x” in a11ytable.R - create_a11ytable function has columns created as factors, not character and this leads the utils-a11ytable.R .append_period function to fail when it calls nchar() – so the process fails.

[we] can fix it by setting options(stringsAsFactors=FALSE) without needing to edit the code in your package. However, I thought you might help others stuck on lower versions of R by hardcoding stringsAsFactors=FALSE in your data.frame call.

Set stringsAsFactors = FALSE and test on R <4.1
