I want to display H = 0.29[0.041] in a plot. H is italicized. I’m using the following code:

annotate("text", x=11.77, y=-0.9, 
                 label=paste0("italic(H)==", sprintf('%.3f', hausman_stats$hausman), 
                              " *"[", sprintf('%.3f', hausman_stats$p_values[2]), "]""),
                 fontface=2, size=textsize, parse = TRUE)

But, it’s showing H = 0.29[]. I’m not sure what’s going wrong here. I was initially using the following code:

# hausman text
        annotate("text",x=11.77, y=-0.9, label=paste0("Hausman",": " ,sprintf('%.3f',hausman_stats$hausman), " [", sprintf('%.3f',hausman_stats$`p-values`), "]"),
                 fontface=2,size=textsize)

I wanted to replace Hausman to an italicized H. So, I am changing the code.
