It is doable to add error bars with base R only as well, but requires more work. In any case, everything relies on the arrows() function. #Let's build a dataset : height of 10 sorgho and poacee sample in 3 environmental conditions (A, B, C) data <- data.frame( specie=c(rep...

Barplot with error bars, annotated by Kruskal-Wallis or ANOVA p-valueSteve Horvath
In Table 1 it is shown that we have created a data frame consisting of two columns. The variable x contains the x-axis labels and the variable y contains the height values of our bars. Let’s try to draw these data with the barplot function: ...
# Add labels inside bars ggbarplot(df2, "dose", "len", fill = "supp", color = "supp", palette = "Paired", label = TRUE, lab.col = "white", lab.pos = "in") # Change position: Interleaved (dodged) bar plot ggbarplot(...
# Add error bars: mean_se # (other values include: mean_sd, mean_ci, median_iqr, ...)# Add labels ggbarplot(df3, x = "dose", y = "len",add = "mean_se", label = TRUE, lab.vjust = -1.6)# Use only "upper_errorbar"ggbarplot(df3, x = "dose", y = "len",add = "...
# Add dot and errors (mean_se)ggbarplot(df3, x="dose", y="len",add=c("mean_se","dotplot"))#>Bin width defaults to 1/30 of the range of the data. Pick better value with#>`binwidth`. # Multiple groups with error bars and jitter pointggbarplot(df3, x="dose", y="len",...
