1 week ago Hi,
I was also trying to find a way to change points and outlines independently as it means you cannot have control over point size in plots with bars (or boxes) displaying error bars and points.
I found a workaround to this problem using your example provided. Turn off points in the add parameter of ggbarplot() and insert them manually using geom_point() instead. Then you can set the size parameter there.
dfm %>% ggbarplot(x = "variable", y = "value", add = c("mean_sd"), color = "Treatment", fill = "Treatment", alpha = 0.5, position = position_dodge()) + geom_point(aes(fill=Treatment,col=Treatment),position = position_dodge(0.8), size=3)
Thank you for this cool tool.
I want to change the size of point and the thicknes of mean_se in ggbarplot together. But I can't assign two "size" parameter in add.params. My question is how can I change the size of point and the thicknes of mean_se in ggbarplot at the same time by using same parameter "size"?
Example
library(ggpubr) df1 = data.frame("group1" = rnorm(24, 20, sd = 2), "group2" = rnorm(24, 30), "group3" = rnorm(24, 40) )
df1[1:6,] = df1[1:6,]/2 df1[7:12,] = df1[1:6,]/3
df1$Treatment = rep(c(paste("Tr", 1:3, sep = "")), each = 8)
dfm = melt(df1, id.vars = "Treatment")
Too thick for error bar
ggbarplot(dfm, x = "variable", y = "value", add = c("mean_sd", "point"), color = "Treatment", fill = "Treatment", alpha = 0.5, position = position_dodge(), add.params = list(color = "Treatment", size=3))
Too small for point
ggbarplot(dfm, x = "variable", y = "value", add = c("mean_sd", "point"), color = "Treatment", fill = "Treatment", alpha = 0.5, position = position_dodge(), add.params = list(color = "Treatment", size=0.5))
