Change "a" in geom_label_repel in R to something else and not just delete it

Question

I am trying to change (not to remove) the "a" that gets displayed by geom_label_repel in the legend. I already found the following Thread: Why does text appear in the legend? that told me how to remove it.

library(ggrepel)

data <- data.frame(xVal,yVal, stringsAsFactors = FALSE)    
plot <- ggplot(data, aes(x=xVal, y=yVal)) +
      geom_point() + 
      geom_label_repel( aes( label=pointName, fill=factor( yVal ) ), nudge_x = 1.25, nudge_y = 1.2 ) +
      scale_fill_manual(values=colorPallet, labels = yVal) 

This Code gives me the following image:

I want to change it so that the "a" in the legend is displaying the numbers i have in the vector pointName. (that are the numbers in the nicture that range from 48 to 96).

Thank you all.

"Guides for geom_text() now accept custom labels with guide_legend(override.aes = list(label = "foo")) (@brianwdavis, #2458)."

As per release 3.0.0.

So here you'd use scale_fill_manual(values=colorPallet, labels = yVal, guide = guide_legend(override.aes = list(label = "foo"))).
