嘿,我怎样才能导出用于制作我为下面的线性回归模型生成的图表的结果表。
d <- data.frame(x=c(200110,86933,104429,240752,255332,75998,
204302,97321,342812,220522,110990,259706,65733),
y=c(200000,110000,165363,225362,313284,113972,
137449,113106,409020,261733,171300,344437,89000))
lm1 <- lm(y~x,data=d)
p_conf1 <- predict(lm1,interval="confidence")
nd <- data.frame(x=seq(0,80000,length=510000))
p_conf2 <- predict(lm1,interval="confidence",newdata=nd)
plot(y~x,data=d,ylim=c(-21750,600000),xlim=c(0,600000)) ## data
abline(lm1) ## fit
matlines(d$x,p_conf1[,c("lwr","upr")],col=2,lty=1,type="b",pch="+")
matlines(nd$x,p_conf2[,c("lwr","upr")],col=4,lty=1,type="b",pch="+")
