R plot - 在一个点上画一个大圆圈 [英] R plot - make a big circle at a point

问题描述

如何制作一个大的点，而不是圆圈中的颜色?

How can I make a point that is a big, NOT colored in circle?

x0 和 y0 只是具有 1 个值的列表.

x0 and y0 are just lists with 1 value.

所以这只是绘制一个值:

So this just plots one value:

points(x=x0,y=y0,col="green",pch=16)

但是这个圆圈有点小，而且是彩色的.

But the circle is sort of small, and it's colored in.

推荐答案

要使单个绘图字符更大，请使用 cex，如下所示:

To make the single plotting character larger, use cex, as in:

points(x = x0, y = y0, col = "green", pch = 16, cex = 10)

请阅读(即使有点乏味)?par 了解基本图形选项.

Please read (even though it's kind of tedious) ?par for base graphics options.

编辑

我想我应该补充(尽管我同意这个问题大部分是重复的)您问题的第二部分只需要 pch 的不同值.听起来像 pch = 1 就是你想要的，但你可以通过 example("points") 看到很多选项.

I suppose I should add (even though I agree this question is mostly a duplicate) that the second part of your question simply requires a different value for pch. Sounds like pch = 1 is what you want, but you can see lots of options via example("points").
