在下面的示例中，标题的第二行与绘图略有重叠。有没有办法通过增加标题和情节之间的间距来解决这个问题？

library(ggplot2)
library(plotly)
library(magrittr)

p1 <- ggplot(iris, aes(x = Sepal.Length, y = Petal.Length)) +
  geom_point() + 
  ggtitle("A REALLY, REALLY, REALLY LONG TITLE THAT I WANT TO\nSPLIT INTO TWO LINES")
p1

ggplotly() %>% config(collaborate=FALSE, cloud=FALSE, displaylogo=FALSE, modeBarButtonsToRemove=c("select2d", "sendDataToCloud", "pan2d", "resetScale2d", "hoverClosestCartesian", "hoverCompareCartesian", "lasso2d", "zoomIn2d", "zoomOut2d"))
