英文:

Why are ylim and xlim not working in pairs plot?

问题

I've translated the code parts as requested:

我一直在尝试调整多个图的坐标轴，使用```pairs```，以使它们都在同一个轴上。这里是一个可重现的例子：

20L), 类别 = "数据框")

并且我的代码：

面板 <- function(x,y){
        points(x,y, col = "蓝色", pch = 21, bg = "蓝色")
        abline(lm(y~x), col="红色")}

我的文本面板 <- function(labels) {
  function(x, y, lbl, ...) {
    if (lbl %in% names(labels)) lbl <- labels[[lbl]]
    text(x, y, lbl, ...)}}

对(x = Corr_data_noppt[1:4], 
      xlim = c(-100, 250),
      ylim = c(-100, 250),
      diag.panel = labels,
      text.panel = my.text.panel(c(LS_avg_RT_diff_L1="L1的RT切换成本", 
                                   LS_avg_RT_diff_L2="L2的RT切换成本",
                                   F_Avg_RT_incong_cong_diff="Flanker RT成本", 
                                   CS_Avg_RT_sw_stay_diff="颜色-形状RT成本")),
      lower.panel = panel,
      font.labels = 1, 
      cex.labels = 1.2,
      upper.panel = NULL) #仅显示矩阵的下半部分

根据其他类似情况，xlim 和 ylim 可以作为参数添加到 pairs 中，但对我来说这并不起作用，我得到一个错误，说它们不被接受：

Error in upper.panel(...) : 
unused arguments (xlim = c(-100, 250), ylim = c(-100, 250))

我尝试将它们分别添加到：

panel <- function(x,y){
        points(x,y, col = "蓝色", pch = 21, bg = "蓝色")
        abline(lm(y~x), col="红色")
        xlim = c(-100, 250)
        ylim = c(-100, 250)}

但这完全没有改变任何东西。

有任何建议吗？

I&#39;ve been trying to adjust the axes of multiple plots using ```pairs```, such that they are all on the same axis. Here&#39;s a reproducible example:

20L), class = "data.frame")

And my code:

panel <- function(x,y){
points(x,y, col = "blue", pch = 21, bg = "blue")
abline(lm(y~x), col="red")}

my.text.panel <- function(labels) {
function(x, y, lbl, ...) {
if (lbl %in% names(labels)) lbl <- labels[[lbl]]
text(x, y, lbl, ...)}}

pairs(x = Corr_data_noppt[1:4],
xlim = c(-100, 250),
ylim = c(-100, 250),
diag.panel = labels,
text.panel = my.text.panel(c(LS_avg_RT_diff_L1="RT Switching costs for L1",
LS_avg_RT_diff_L2="RT Switching costs for L2",
F_Avg_RT_incong_cong_diff="Flanker RT costs",
CS_Avg_RT_sw_stay_diff="Colour-Shape RT costs")),
lower.panel = panel,
font.labels = 1,
cex.labels = 1.2,
upper.panel = NULL) #show only the low half of the matrix

According to other cases on here, ```xlim``` and ```ylim``` can be added as arguments to ```pairs```, but that doesn't work for me and I get an error that they are not taken as such: 

Error in upper.panel(...) :
unused arguments (xlim = c(-100, 250), ylim = c(-100, 250))

I tried alternatively adding them onto:

panel <- function(x,y){
points(x,y, col = "blue", pch = 21, bg = "blue")
abline(lm(y~x), col="red")
xlim = c(-100, 250)
ylim = c(-100, 250)}

But that changed absolutely nothing. 
Any suggestions?

你需要通过使用省略号 (...) 结构为你的自定义面板函数允许额外的参数（例如 xlim）：

panel <- function(x, y, ...){
points(x,y, col = "blue", pch = 21, bg = "blue")
abline(lm(y~x), col="red")}

You need to allow additional arguments (e. g. `xlim`) to your custom panel function by [using the dot-dot-dot (`...`) construct][1]:

panel <- function(x, y, ...){
points(x,y, col = "blue", pch = 21, bg = "blue")
abline(lm(y~x), col="red")}
