给stat_smooth添加一个偏移量 [英] Adding an offset to stat_smooth

问题描述

我正在处理一个数据集，我必须对某些数据进行转换以适合曲线拟合。我使用ggplot2来绘制它，并且可以在转换的数据上使用stat_smooth来获得拟合，但是然后想要将结果叠加在正确的数据点上。

作为玩具的例子，假设我有
$ b $ qplot（1:10,1:10）+ stat_smooth（formula = y + 1〜x，method =lm）

但我想将stat_smooth行向下移一位（除了从公式中取+1）。这可能吗？

解决方案

有时候，事情可能会非常明显：

<$ （公式=（y + 1）-1〜x，method =lm）

I'm working with a dataset where I have to transform some data for a curve fit. I'm plotting it using ggplot2, and can use stat_smooth on the transformed data to get the fit, but then want to overlay the result on the correct datapoints.

As a toy example, let's say I had

qplot(1:10, 1:10)+stat_smooth(formula=y+1~x, method="lm")

But I want to shift the stat_smooth line down by one (other than by taking the +1 out of the formula). Is this possible?

解决方案

Sometimes things can be very obvious :

qplot(1:10, 1:10)+stat_smooth(formula=(y+1)-1~x, method="lm")

If you can raise it 1 by adding 1 to y, you can lower it 1 by substracting 1 from y. ;-)
