r - Smooth a density plot so that it doesn't appear saw toothed

Question

I have made a density plot in R. I want to get rid of the saw tooth pattern and have it be entirely smooth. The reason that it appears saw tooth is because the values of x$PLCO2 are all whole numbers. But I want to smooth the plot for aesthetic reasons. Any idea on how to do that?

plot(density(x$PLCO2))

Answer 1

您可以通过增加带宽（bw）使密度图更平滑

plot(density(x$PLCO2, bw = bw_bigger))

Answer 2

或者，您可以使用adjust.

plot(density(x$PLCO2, adjust = 2))

文档说：

adjust: 实际使用的带宽是adjust*bw. 这使得指定诸如“默认一半”带宽之类的值变得容易。
