放大R中现有图中的子图

Question

我在R中有以下图。我想在现有的绘图形式x =[0, 2]和y=[0, 2]中有一个子图，我想要放大该子图。我怎么能在R？中做到这一点？

 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

您可以这样做：

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)

Answer 2

您可以使用绘图函数的xlim和ylim参数更改绘图的限制。例如

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