更改gbm局部图上的x和y标签

Question

我无法在gbm模型的局部图上更改x和y标签.我需要为期刊文章重命名它们.

我读了这个并创建了如下图:

library(gbm)
final<- readRDS(final_gbm_model)
summary(final, n.trees=final$n.trees)

以下是摘要输出:

我可以创建一个部分依赖图如下:

plot(final,"ProbMn50ppb",n.trees=final$n.trees)

但是,如果我尝试设置标签参数,我会收到以下错误:

 plot(final,"ProbMn50ppb",n.trees=final$n.trees,ylab="LNNO3")

Error in plot.default(X$X1, X$y, type = "l", xlab = x$var.names[i.var],  : 
  formal argument "ylab" matched by multiple actual arguments

如何更改y轴和x轴标签？

Answer 1

该plot.gbm函数将自己的名称传递给通用绘图函数,因此两者相互冲突.因此,您将无法在该模式下以您希望的方式自定义绘图.但是当你设定时,作者确实提供了另一种选择return.grid=TRUE.它不是构建绘图,而是输出数据本身.然后,您可以将其用于包括ggplot2在内的任何绘图.

plotdata <- plot(gbm1, return.grid=TRUE)
plot(plotdata, type="l", ylab="ylab", xlab="xlab")
