[英]R: Multiple Linear Regression error
I am having hard times running the lm()
function and understanding the error. 我在运行
lm()
函数并理解错误时遇到了困难。
So, my script is this: 所以,我的脚本是这样的:
#! /usr/bin/env/ Rscript
meteodata <- read.table("/path/to/dataset.txt", header=T)
meteodata
summary(meteodata)
plot(meteodata)
lmodel <- lm(temperature~altitude+sea.distance, data=meteodata)
And the console output is this: 控制台输出是这样的:

Warning messages:
1: In model.response(mf, "numeric") :
using type = "numeric" with a factor response will be ignored
2: In Ops.factor(y, z$residuals) : - not meaningful for factors
I ve read some similar questions here and there but i still can't figure out what i am doing wrong. 我到处都读过一些类似的问题,但我仍然不知道自己在做什么错。 I need
temperature
as my response y variable to be calculated by the independent x1,x2 altitude
and sea.distance
variables. 我需要
temperature
作为我的响应y变量,由独立的x1,x2 altitude
和sea.distance
变量来计算。
Any help will be appreciated, just try to be specific. 任何帮助将不胜感激,只是尝试具体。 Thanks in advance
提前致谢
