ggplot2

Dear R Community,

Below is a problem with a simple ggplot2 graph. The code returns the error
message below.

Error: stat_count() must not be used with a y aesthetic.

My code is below and the data is attached as a ?text? file.



# Graph of the probabilities

library(digest)

library(DT)

datatable(probability)

str(probability)

probability$Fertilizer <- as.factor(probability$Fertilizer)

str(probability)

library(ggplot2)

plot1 <- ggplot(probability, aes(x=Fertilizer, y=prob)) +
geom_bar(aes(fill=Treatment))

plot1



Thanks.

Best regards,

James F. Henson

Hi James,

If you want to specify the y-values, you need to use stat="identity" as
below:

ggplot(probability, aes(x=Fertilizer, y=prob)) +
geom_bar(stat="identity", aes(fill=Treatment))


best,
