英文:
Base R: Plotting beyond the plotting window despite using xlim
问题
这个问题最好由以下代码行来描述：
> plot(1:100, 1:100, xlim = c(0, 50))
它生成了以下内容，其中图形超出了窗口范围。我不认为我以前在R中曾经遇到过这种情况。
英文:
The question is best described by this line of code
> plot(1:100,1:100, xlim = c(0,50))
It generates the following, which has the graph going outside of the window. I don't believe I have ever experienced this before in R.

当expand（xpd）参数被设置为NA（通过plot函数或全局设置如par(xpd = NA)），图形元素将扩展到图形之外。将par(xpd = FALSE)设置为在绘图区域内绘图（在框内 - 默认设置）；将xpd = TRUE设置为在图形区域内绘图（在边距内），而xpd = NA允许在整个图形设备上绘图。请参阅?par中的xpd部分。
您可以通过重新启动R或运行par(xpd = FALSE)来恢复默认设置。
英文:
When the expand (xpd) parameter is set to NA (by the plot function or via global setting like par(xpd = NA)), plot elements will extend beyond plot. Setting par(xpd = FALSE) restricts plotting to the plot region (inside the box - the default); setting (xpd = TRUE) restricts plotting to the figure region (within the margins) and xpd = NA allows plotting over the entire graphics device. See the xpd section of ?par.
You can return to the default setting by restarting R or running the line par(xpd = FALSE).
