Using geom_errorbar in ggplot2 results in “Error: geom_errorbar requires the following missing aesthetics: ymin, ymax”

I wanted to create a visualisation for some data I had collected using ggplot2. Everything works fine except I cannot add error bars for some reasons. The code I used is the following

graph2 <- ggplot(enth_comb, aes(saturated, eocv, color=oil))
graph2 <- graph2 + geom_point()

This worked fine and resulted in the graph I expected. Then I added the following

graph2 <- graph2 + geom_errorbar(aes(ymin = v_lowlim, ymax = v_highlim))

This gives me the error "Error: geom_errorbar requires the following missing aesthetics: ymin, ymax" despite having provided ymin and ymax. I also tried adding an x value and removing 'aes' but it resulted in the same error.

The data is the followingData Frame

I appreciate any help or suggestions.

Edit: Added output of dput(enth_comb)

structure(list(oil = structure(c(4L, 6L, 3L, 5L, 2L, 1L), .Label = c("coconut", 
"palm", "peanut", "rapeseed", "rice", "sunflower"), class = "factor"), 
    saturated = c(8L, 11L, 17L, 25L, 82L, 88L), sonounsaturated = c(64L, 
    20L, 46L, 38L, 7L, 12L), Polyunsaturated = c(28L, 69L, 32L,

Try graph2 + geom_errorbar(data=enth_comb,aes(ymin = v_lowlim, ymax = v_highlim)) – Duck
It gives me the same error – ben
Try: ggplot(enth_comb, aes(saturated, eocv, color=oil))+ geom_point()+ geom_errorbar(aes(ymin = v_lowlim, ymax = v_highlim)) – Duck
I have added as a solution, if you like you could accept the answer if this was helpful for you :) – Duck
Would you mind adding a piece of your dataset as data instead of a screenshot? Since your dataset is show short you could copy and paste the result of dput(enth_comb) into your question. Just from looking I don't see a reason the code you wrote doesn't work and so it seems worthwhile to test further in case this is a bug. – aosmith

The full solution would be concatening all elements:

ggplot(enth_comb, aes(saturated, eocv, color=oil))+
   geom_point()+
geom_errorbar(aes(ymin = v_lowlim, ymax = v_highlim))
