关于ggplot2中geom_smooth函数参数se的含义及其缩写来源的技术咨询

Hey there! Let's unpack this question step by step:

What's the purpose of the se parameter? #

In geom_smooth(), the se parameter controls whether to render the confidence interval that surrounds the fitted smooth line. By default, it's set to TRUE—you can tweak the confidence level with the level parameter (for example, level = 0.9 would give you a 90% confidence interval). Setting se = FALSE will turn off this interval entirely.

Where do the s and e in se come from? #

The shorthand se stands for Standard Error:

• The s is the first letter of Standard
• The e is the first letter of Error

Since the confidence interval displayed is derived from the standard error of the smooth fit, using this shorthand makes perfect sense for the parameter name.
