I want to create a nice boxplot with this dataset (I called the data set 'data_N3_minmax'):
I first used this code:
label=c("V1", "V2", "V3", "V4", "V5", "V6", "V7")
boxplot(data_N3_minmax, xlab="", ylab="", names=label)
This code produces this graph:
You see that there is a huge difference between V3 and the rest. Therefore, I wanted to incorporate an y-axis gap. I started with the gap.boxplot function from the package plotrix. However, I ran into a problem that I don't know how to fix. I used this code:
library("plotrix")
label=c("V1", "V2", "V3", "V4", "V5", "V6", "V7")
gap.boxplot(data_N3_minmax, gap=list(top=c(30,1000), bottom=c(NA,NA)), xlab="", ylab="", names=label)
I only want to get one gap between the values of V3 and the other boxplots, so I do not use the bottom gap. Sadly, I got this error message: Error in gap.boxplot(data_N3_minmax, gap = list(top = c(50, 1000), bottom = c(NA, : gap cannot include the median, interquartiles or the staples.
This confuses me because the gap I want to include (between 30 and 1000) does not include the median, interquartiles or the staples. Can anyone help me to solve this problem or show me how I can incorporate an axis gap in another way? I mostly have experience with base R plotting and no experience with ggplot, so I would prefer to do this in base R.
