绘图窗口中的 corrplot 边距

Question

I entered the commands below to develop a core plot. It works, but the plot shows up sandwiched against the bottom margin. Changing par(mar=c(5, 4, 4, 2) + 0.1) parameters has no impact on the placement of the corrplot. Ideas?

library(corrplot)
a <- seq(1,10,1)
b <- seq(2,20,2)
c <- seq(3,30,3)
z <- data.frame(a,b,c)
corrplot(cor(z))

Answer 1

将边距直接添加到corrplot()调用中，如下所示：

corrplot(cor(z), mar = c(1, 1, 1, 1))

Answer 2

I was running into trouble with this because setting margins within the function still clipped the axis labels, which in my case were relatively long site names. If you have long names for the rows/columns, in addition to using a mar() call within corrplot(), you may first need to call par(xpd = TRUE) to allow plotting in the margins.
