create a table with ggplot

[ernijs12]

Hi,

I have a table of data, example:

tibble::tribble(
~Item, ~'0', ~'1',
"123", '30', '40',
"213", '20', '50',
"321", '10', '60',
)

I am trying to make a bar plot with ggplot2, that shows each material on x axis and the value of column '1' on y axis

I tried this code:

ggplot(dt, aes(x = Material, y= '1', group = Material, color = Material))+
  geom_bar(stat = "identity")

but this is the result:

[Ven]

@ernijs12

'1'

This variable should not be in single-quotes.

`1` # Should use the grave accent 

[ernijs12]

Now it looks like this

[Ven]

Based on this, I assume "Material" is numeric, which is why it's structuring the x-axis in that way.

[ernijs12]

is there a way to convert it to categorical?

got it used as.character and it looks good now, thank you very much!!!
