R: Boxplot names overlap with x axis

I have a probably very easy question but I just can't find a proper solution for it. I have the following code:

    data <- as.data.frame(matrix(rnorm(30),15,2))
    names(data) <- c("BoxplotData1","BoxplotData2")
    boxplot(data, names = c("Box \n Plot \n Data1","Box \n Plot \n Data2"))
    axis(1, at=1:2,labels = FALSE)

which gives me an output as shown in the plot below. I would now like to change the position of the boxplot names so that there is no overlapping anymore. I just find ways to increase the distance between axis title and the names, but I just don't find a way to solve my issue.

Thank you for any comment! enter image description here

You can change the graphical parameters in par

par(mgp = c(3, 3,0))#mgp sets position of axis label, tick labels and axis
boxplot(data, names = c("Box \n Plot \n Data1","Box \n Plot \n Data2"))

If your labels are very long, you might also need to set mar to increase margin size.

Do the boxplot with no names, add them using axis with the line parameter to give them some space. Use lwd=0 to suppress redrawing of the axis lines and ticks:

boxplot(data,names=c("",""))
axis(1,at=1:2, c("Line1\nLine2\nLine3","Box\nPlot\nLine3"),
  line=2, lwd=0)
