在R中使用gamlss :: lms选择百分曲线 [英] Selecting Percentile curves using gamlss::lms in R

问题描述

我正在使用gamlss包中的示例代码绘制百分位数曲线：

I am using example code from gamlss package to draw percentile curves:

library(gamlss) 
data(abdom)
lms(y,x , data=abdom, n.cyc=30)

正在绘制自己的一组百分位曲线。如何选择仅绘制第10、50和90％百分位曲线？我也想避免绘制点，以便仅绘制曲线。
感谢您的帮助。

It is drawing its own set of percentile curves. How can I choose to draw only 10th, 50th and 90th percentile curves? Also I want to avoid plotting of points so that only curves are drawn. Thanks for your help.

推荐答案

阅读帮助页面总是一个好主意：

It's always a good idea to read the help pages:

> centiles(h,xvar=abdom$x, cent=c(10,50,90), points=FALSE)
% of cases below  10 centile is  8.688525 
% of cases below  50 centile is  50.16393 
% of cases below  90 centile is  90
