如何在一行中使用多个表达式 [英] How to use more than one expression in a row

问题描述

我是新来的，我正在努力弄清楚，如何写一些类似嘿，伙计们，这是我的情节（\\\
）8< =（小于或等于）x< = 10 在我的情节标题中。

我尝试过这样的事情：

 <$ c $ $ c 
 mtext（c（表达式（8≤x）），表达式（x <= 10） ，side = 3）
  

这不完全是我想要的，但是8（少于或等于）xx （少于或等于）10，这两个表达方式打印在主标题下方（这是很酷），但在同一个地方，这几乎没用：）

我还试过：

  plot（1:10，main = bquote（paste（8& x，x = 10，sep =，）））
  

什么样的我想（除了分隔符似乎被完全忽略），但我不能添加更多的文本。输出：8（少于或等于）xx（小于或等于）10。

当我尝试

  plot（1:10，main = paste（x）bquote（paste（x <= 8，z <= 10，sep =）） ））
  

输出完全激怒我：标题是：xpaste（\\\
） xx <= 8（\\\
）xz = 10（\\\
）x（（\\\
）是换行符，其他字符正好是打印的）

所以有可能用多个操作符打印表达式？

解决方案

  plot（1:10，main =〜bold（atop（嘿，伙计们，这是我的情节，{ 8< = x}< =10）））
  

c $ c> windows（）设备看起来像这样：

REVISED 间距，使第二行有点大，以匹配第一行。添加rbatt的顶部想法。进一步简化。

I am new to R and I am trying to figure out, how to write something like "Hey guys, this is my plot for (\n)8 <=(less than or equal) x <= 10" in my plot-title.

I tried something like this:

plot(1:10, main="Hey, guys, this is my plot for \n")
mtext(c(expression(8 <= x),expression(x <= 10), side=3)

This gives not exactly what I want but "8 (less or equal) x x (less or equal) 10", and those two expressions are printed in a line below the main title, (which is pretty cool) but in the same place, which is pretty much useless :)

I also tried:

plot(1:10, main=bquote(paste(8 <= x, x <= 10, sep=",")))

What kind of does what I want (except the seperator seems to be completely ignored), but I cant add further text. Output: "8 (less or equal) xx (less or equal) 10".

And when I tried

plot(1:10, main=paste("x",bquote(paste(x <= 8,z <= 10,sep=" ")),sep=" "))

the output irritated me completely: the title was: "xpaste (\n) x x <= 8 (\n) x z <= 10 (\n) x" (the (\n) is a line break, the other characters are exactly what is printed)

So is there a possibility to print expressions with more than one operator?

解决方案

Try this:

 plot( 1:10, main = ~ bold(atop("Hey, guys, this is my plot for", {"8" <= x} <= "10")))

On the windows() device it looks like this:

REVISED spacing and made 2nd line a bit larger to match first line. Added rbatt's atop idea. Further simplification.
