ggplot legend superscript

Hi,

could you please help me with the superscript in the legend?

image

ggplot(data = sf) +
  geom_sf(aes(fill = value), colour = "grey10",size=0.2)+
  scale_fill_gradient2(low = "#376092",
                       mid = "#DCE6F2",
                       high="#CD3C33",
                       midpoint = 10.6,
                       labels= function(x) paste0(format(round(x, 0), nsmall = 0)," tun/km^2"))+
  labs(title = expression(paste("Emise CO"["2"]*"  2017")),
       fill = "") +
  theme(legend.text.align = 1,
        legend.title.align = 0.5,
        legend.text=element_text(size=7),
        plot.title = element_text(hjust = .1,vjust=0.2,size=18),
        panel.grid.major = element_blank(), 
        panel.grid.minor = element_blank(),
        panel.background = element_blank(),
        axis.text.x=element_blank(),
        axis.text.y=element_blank(),
        axis.ticks=element_blank(),
        axis.title.x=element_blank(),
        axis.title.y=element_blank())+
  geom_sf_text(aes(label =nazev),size=3,family="sans")+
  annotate("text",x = 14.5, y = 49.8, label = "Středočeský",size=3)+
  annotate("text",x = 17.3, y = 49.6, label = "Olomoucký",size=3)+
  annotate("text",x = 16.7, y = 49.0, label = "Jihomoravský",size=3)+
  ggsave(filename="kraj_emise_CO2_km.png",dpi="print")

Thank you!

I think when you build the labels for your scale fill manual you have opportunity to use expression like you did for your main title.
I'd play around with it but I don't have your sf so I can't.

typo ? str2expression

Sorry, I meant str2expression().

Error in str2expression(paste0(format(round(x, 0), nsmall = 0), " ~ tun/km^2")) :
could not find function "str2expression"

not even in R Documentation

str2expression joined base R in version 3.6.0

This should work the same:

labels= function(x) parse(text = paste0(format(round(x, 0), nsmall = 0), " ~ tun/km^2")))

How can I make sf reproducible?
I thought ^ would make it superscript.

for a reproducible sf, perhaps try rmapshaper::ms_simplify to reduce the geometry as much as possible. it has a keep param which is % of geometry to keep.

If its small enough you might then dput() as normal.

Using expression seems a good way to go, but you have trouble getting a vector (since expression won't evaluate format, so will dump the input vector all at once in a single expression). A solution is to use parse(text = ...) or equivalently str2expression() to execute format, make a string with paste, then turn it into an expression.

One caveat is that the expression has to be valid, so you need an operator (e.g. * or ~) between the number and the unit. This works on a different example:

labels = function(x) str2expression(paste0(format(round(x, 0), nsmall = 0), " ~ tun/km^2"))

This should do the job.
