Problem with NAs in the first row

[jtr13]

Thank you for a fantastic package!

There seems to be an odd error: If there is an NA in the first row, the plot doesn't render.

For example, this works:

df <- data.frame(a = 1:2, b = 3:4, c = c(5, NA))
parcoords::parcoords(df)

but this doesn't:

df <- data.frame(a = 1:2, b = 3:4, c = c(NA, 5))
parcoords::parcoords(df)

@jtr13 thanks so much for filing the issue and reminding me that there are users of parcoords :) As soon as I read, this should have been obvious, but I had not considered before. Unfortunately the underlying library does not currently support. I would think naniar https://cran.r-project.org/web/packages/naniar/vignettes/naniar-visualisation.html would give us some thoughts on how to treat NA. It seems like we would need a custom d3 scale that includes NA, since we lose information by not showing and I think lose pattern/connection if we depict as a gap.
