Re: [R] plot xaxp issue

Hello, I figured out that the code should be boyline<-lm(body_weight ~ body_length, data=subset (together,,sex=="boy")) However, the "" could be omitted if the field name happened to be numeric, such as 1, 2, or 3. Please kindly explain why the "" could be omitted for numbers. Thanks again. Ela

Re: [R] plot xaxp issue

Hi Instead of two plots with par(new = TRUE) try to put boys and girls together (quite natural thing, they will be pleased 8-) together <- rbind(boy, girl) together$sex <- factor(rep(c("boy", "girl"), c(8,7))) plot(together$body_length, together$body_weight, , col=c("firebrick3","saddlebro
