将上部和下限设置为绘制的矩阵中绘制的值。matrix
我正在尝试绘制矩阵的值，并且需要使用library（plot.matrix）进行操作。我的问题是，某些矩阵具有极高的值，这些值偏向图，并且不允许我以图形方式观察非外部词的值的差异。
为了说明这一点，想象一下我想绘制以下矩阵：
> a <- matrix(1:9, nrow=3, byrow=TRUE)
> a[1,3] <- 1000
> a
[,1] [,2] [,3]
[1,] 1 2 1000
[2,] 4 5 6
[3,] 7 8 9
因此，我想避免在绘制矩阵时考虑a [1,3]值（我不希望在定义调色板或其他情节设置的断裂）。
检查文档后 https://cran.r-project.org/web/packages/plot.matrix/vignettes/vignettes/plot.matrix.htmli 没有找到直接允许我的函数plot.matrix的任何参数定义要绘制的值范围 - 类似于x.lim或y.lim的论点。
尽管我已经还有其他一些解决方案：
- 重新定义矩阵替换这些值
na - 使用空白的适当定义，但
我想知道是否有任何直接论证fuction plot（...）可以直接执行此操作。
I am trying to plot the values of a matrix and I need to do it using the library(plot.matrix). My problem is that some of the matrix have extremely high values which bias the plot and do not allow me to observe graphically the differences of the non-outliers' values.
To illustrate this, imagine I want to plot the following matrix:
> a <- matrix(1:9, nrow=3, byrow=TRUE)
> a[1,3] <- 1000
> a
[,1] [,2] [,3]
[1,] 1 2 1000
[2,] 4 5 6
[3,] 7 8 9
Therefore, I would like to avoid considering the a[1,3] value when plotting the matrix (I do not want it to be considered when defining the breaks of the palette or other plot settings).
After checking the documentation https://cran.r-project.org/web/packages/plot.matrix/vignettes/plot.matrix.htmlI did not find any argument for the function plot plot.matrix which directly allows me to define the range of values to plot - something similar to the x.lim or y.lim arguments.
Although I already have some other solutions:
- Redefine the matrix substituting these values for
NA - Use an adequate definition of breaks
I was wondering if there is any direct argument to the fuction plot(...) that allows me to do this directly.

您可以使用
break参数手动设置限制：甚至设置所有个人断裂：
You can use the
breaksargument to set the limits manually:Or even to set all the individual breaks:
