Change X-axis Labels in cplot
问题
我有一个逻辑回归模型，想使用 cplot 函数绘制每个变量的平均边际效应。但我有一个分类变量，其标签很长，导致 cplot 产生重叠的 x 轴标签：
cplot(model,"Region", xlab = "Dwelling's Region")
如图所示，由于标签很长，它只显示了一半。我要如何创建一个没有 x 标签，只有数字（从1到12）的图表。我尝试了这个但没效果：
cplot(model,"Region", xlab = "Dwelling's Region")
axis(1, at = 1:12, labels = 1:12)
英文:
I have a logistic regression model and I want to plot the average marginal effects of each variable using the cplot function. But I have a categorical variable where the labels have long names, which causes the cplot to produce overlapping x-axis labels:
cplot(model,"Region", xlab = "Dwelling's Region")
As you can see, because the names are long, it displays only half of them. How can I create a plot without x-labels, but only numbers, from 1 to 12. I tried this but it didn't work:
cplot(model,"Region", xlab = "Dwelling's Region")
axis(1, at = 1:12, labels = 1:12)

似乎cplot()将额外的参数传递给默认的图形方法。关闭绘制x轴的标准方法是通过设置xaxt='n'。在help(par)中搜索xaxt。
在您的情况下，应该这样做：
cplot(model, "区域", xlab = "住宅区域", xaxt='n')
axis(1, at = 1:12, labels = 1:12)
英文:
Seems like cplot() passes additional arguments to default graphics methods. The standard way to turn-off the drawing of x-axis is by setting xaxt='n'. Search for xaxt in help(par).
In your case this should work:
cplot(model,"Region", xlab = "Dwelling's Region", xaxt='n')
axis(1, at = 1:12, labels = 1:12)
