Hi, I want to put spaces between each pair of bars in my barplot.

This is my code

ggplot(Germ, aes(x = G, y = T, 
             color = c('WT', 'at5g01950')[2 - (as.numeric(G) %% 2)])) +
geom_bar(position="dodge", stat="identity") +
geom_boxplot(width = 0.5, color = "black", alpha = 0.2, 
             position = position_dodge(0.9)) + 
theme_minimal() + 
theme(plot.background = element_rect(fill = "white") ,
      panel.grid.minor = element_blank()) +
labs(color = '')

This is my barplot

enter image description here

It would be nice to add the space of a bar, or even less, bewteen, for example, bars pairs 1,2 and 3,4, and so on.

Thank you

This is a general R question and not related to bioinformatics, thus is likely better for stackoverflow. After a quick google search you likely want to tinker with the width parameter within the geom_bar layer. See this SO post: https://stackoverflow.com/questions/6085238/adding-space-between-bars-in-ggplot2

this isn't really a bioinformatics question, but you alter the distances using both position=position_dodge(width=0.5) and width=0.5 in your boxplot and bar geometries.

Also, to properly dodge and color the bars create a column with the group and then just pass the column name to fill= in the aesthetics function of ggplot.
