强制x轴和y轴在R中的（0,0）处相遇

It's reasonable to set the plot region just around the data points, and not requiring the two meet at the origin, but sometimes it's desirable to have exactly that.

将绘图区域设置在数据点周围是合理的，并且不需要两者在原点相遇，但有时候确实需要这样。

I am trying to achieve that with the grid package but not getting what I want:

我试图用网格包实现这一点，但没有得到我想要的东西：

require(grid)
grid.newpage()
pushViewport(plotViewport(c(5, 5, 5 ,5)))
pushViewport(dataViewport(1:10, 1:10))
grid.points(1:10, 1:10, default.units='native')
grid.xaxis(at=0:10)
grid.yaxis(at=0:10)

How can this be done in both the grid system and the tranditional R graphics system?

如何在网格系统和传统的R图形系统中完成？

I think your problem comes from the extension argument in dataViewport

我认为你的问题来自dataViewport中的扩展参数

require(grid)
grid.newpage()
pushViewport(plotViewport(c(5, 5, 5 ,5)))
pushViewport(dataViewport(0:10, 0:10, extension=c(0,0)))
grid.points(1:10, 1:10, default.units='native')
grid.xaxis(at=0:10)
grid.yaxis(at=0:10)

In base graphics,

在基础图形中，

plot(1:10, 1:10, xaxs="i", yaxs="i", xlim=c(0,10), ylim=c(0,10))
