ggplot(dataset, aes( x = Norm, fill = Condition, y=log2(measure))) + geom_boxplot() +
            scale_fill_manual(values=c("brown1","darkolivegreen4","burlywood3")) + theme_classic() + 
            labs(title="Comparison",x="Norm", y = "counts") +
            scale_fill_continuous(labels = paste("condition1", "condition2", "condition3"))

I am trying to change the labels of the legend. Currently, it shows the labels that are present in my dataset. However, I want to change it to "condition1", "condition2", "condition3". Above is the code I am trying. It gives me following error.

    Scale for 'fill' is already present. Adding another scale for 'fill', which will replace the existing scale. Error: Discrete value supplied to continuous scale In addition: Warning message: Removed 18 rows containing non-finite values (stat_boxplot).

Could someone help me here? TIA
