Doesn't work in R 4.0.3

[albert-ying]

Hi, I just found visidata and this amazing package when I was frustrated with excel. Visidata itself works well to me, but I tried the example of this package, it doesn't work somehow.

Steps

1. Open R with R --vanilla, everything in my .visdatarc are commented out.
2. rvisidata::vd(iris)

It gives

I have the exact same issue! :/

[torbjorn-sjoberg-voi]

I did some quick testing and there seems to be something off with the json part of the code!

Removing line 9-13 in main.r made the code for me.

I can't reproduce. I pushed a potential fix, can you please verify if you still have this error?

[torbjorn-sjoberg-voi]

Sadly, did not work.

It is very strange howver foxusing on a row displays the values correctly!

Same here, seems like some weird thing happens to the numeric columns. Also when I try to edit the cells, the character column works fine, but for the numeric columns, it gives me an error TypeError: 「NoneType' object does not support item assignment| 

Also I'm using macOS, not sure if this is related to the problem of reproducing.

[torbjorn-sjoberg-voi]

macOS here aswell

Hm, looks like the json serializer is wrapping scalars weirdly or something.

@albert-ying rvisidata doesn't support editing the data in any meaningful way, so I advise you against that, but what you're describing is still a bug

@torbjorn-sjoberg-voi hi - can you provide a sessionInfo like @albert-ying ?

[strazto]

I can't reproduce this on R 3.6.* rn

Is this issue still relevant? Will otherwise close it.
