放大現有繪圖中的子圖R

Question

我在R中繪製了以下繪圖。我希望​​在現有繪圖形式x =[0, 2]和y=[0, 2]中有一個子圖，我也想放大該子圖。我如何在R中做到這一點？

lin <- data.frame(x = c(0:6), y = c(0.3, 0.1, 0.9, 3.1, 5, 4.9, 6.2)) 
linm <- lm(y ~ x, data = lin, subset = 2:4) 
plot(y ~ x, data = lin) 
abline(linm) 

Answer 1

您可以使用xlim和ylim參數更改繪圖函數的繪圖極限。例如

plot(y~x, data = lin, xlim=c(0,2), ylim=c(0,2)) 

Answer 2

比如，你可以這樣做：

lin <- data.frame(x = c(0:6), y = c(0.3, 0.1, 0.9, 3.1, 5, 4.9, 6.2)) 
linm <- lm(y ~ x, data = lin, subset = 2:4) 
plot(y ~ x, data = lin) 
abline(linm) 
## to overlap the 2 plots 
par(new=TRUE, oma=c(3,1,1,2)) 
## create a layout to plot the subplot in the right bottom corner 
layout(matrix(1:4,2)) 
## use xlim and ylim to zoom the subplot 
plot(y ~ x, data = lin,xlim=c(0,2), ylim=c(0,2)) 
abline(linm)
