Adding geom_ribbon to geom_line from secondary dataframe


I'm trying to display my model fit and data points on the same plot with ggplot, but can't figure out how to add my calculated SE bands (pred$conf.low, pred$conf.high) to my model line (pred$predicted).

> head(toad2,5)
    num   DO
753   0 8.41
755   0 8.27
756   0 8.31
757   0 8.04
758   0 7.77

> str(toad2)
'data.frame':   640 obs. of  2 variables:
 $ num: int  0 0 0 0 0 0 0 0 0 0 ...
 $ DO : num  8.41 8.27 8.31 8.04 7.77 7.43 7.54 7.37 7.33 6.75 ...
 - attr(*, "na.action")= 'omit' Named int [1:1005] 1 2 3 4 5 6 7 8 9 10 ...
  ..- attr(*, "names")= chr [1:1005] "1" "2" "3" "4" ...

fit <- glmmTMB(num ~ DO, family=nbinom2, ziformula = ~0, dispformula = ~1, toad2, REML = FALSE)

pred <- ggpredict(fit, terms = "DO")

> pred
# Predicted counts of num

DO | Predicted |       95% CI
-----------------------------
 0 |      0.11 | [0.05, 0.24]
 2 |      0.15 | [0.09, 0.25]
 4 |      0.20 | [0.14, 0.27]
 6 |      0.26 | [0.21, 0.33]
 8 |      0.35 | [0.25, 0.49]
10 |      0.46 | [0.27, 0.80]
12 |      0.62 | [0.29, 1.33]
16 |      1.10 | [0.32, 3.79]

How would I add the 95% confidence intervals to this geom_line from ggeffects/data.frame "pred"?

ggplot(data = toad2, aes(x = DO, y = num)) + 
  geom_point(color='blue') +
  geom_line(color='red',data = pred, aes(x=x, y=predicted)) 

enter image description here

My attempt:

ggplot(data = toad2, aes(x = DO, y = num)) + 
  geom_point(color='blue') +
  geom_line(color='red',data = pred, aes(x=x, y=predicted, ymin = conf.low, ymax = conf.high)) 

Warning message:
In geom_line(color = "red", data = pred, aes(x = x, y = predicted,  :
  Ignoring unknown aesthetics: ymin and ymax

"pred" data:

Solution

  • Using a geom_ribbon you could do:

    library(ggplot2)
    
    ggplot() +
      geom_ribbon(data = pred, aes(x=x, ymin = conf.low, ymax = conf.high), alpha = .3, fill = "red") +
      geom_line(color = "red", data = pred, aes(x = x, y = predicted))
