R语言基础问题，请看以下代码，为什么“fitted values”和"residuals"里没有值？

Question

> temperaturemor=read.table("E:/temperature.csv",header=T,sep=",")
> names(temperaturemor)
[1] "Mortality" "Temperature"
> mortality=temperaturemor$Mortality
> temperature=temperaturemor$Temperature
> temperaturemor.reg=lm(mortality~temperature)
此处省略无数
> names(temperaturemor.reg)
[1] "coefficients" "residuals" "effects" "rank"
[5] "fitted.values" "assign" "qr" "df.residual"
[9] "xlevels" "call" "terms" "model"
> fitted.values=temperaturemor.reg$fitted.values
> residuals=temperaturemor.reg$residuals
> names(fitted.values)
[1] "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "12" "13" "14"
[15] "15" "16"
> names(residuals)
[1] "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "12" "13" "14"
[15] "15" "16"
为什么！！！！！！！

Answer 1

如果要做线性回归的话不应该是：lm(mortality~1+temperature)???，可以尝试一下。

Answer 2

R语言，不懂，我回C语言
