Question

我愿在R. The

例如,我要印刷一下数学休眠=数学休眠=数学-数学-参数。在地物名称中,数学温度为0.13美元,并且仍在评估某些变量的价值。我的最好解决办法是:

lambda <- 4
plot(1:10,1:10)

mtext(bquote(paste(d*bolditalic(x)[italic(t)] == alpha*(theta - bolditalic(x)[italic(t)] )*d*italic(t) +  .(lambda) * d * italic(B)[italic(t)] )), line=2.25,cex=2)

或

require(ggplot2)
qplot(1:10, 1:10) + opts(title=bquote(paste(d*bolditalic(x)[italic(t)] == alpha*(theta - bolditalic(x)[italic(t)] )*d*italic(t) +  .(lambda) * d * italic(B)[italic(t)] )), line=2.25,cex=2)

This question almost solves this, but I loose the ability of bquote to display the numerical value of a variable (lambda in my example). Is there a way to combine these so I can have italic greek letters (the standard f或mat f或 variables, e.g. as done by tex) and evaluate at specific values?

Is there a much better way where I can simple write tex-syntax f或 equations and add them to my graphs?

Answer 1

您不妨查看tikzDevice。 http://cran.r-project.org/web/ Packages/tikzDevice/vignettes/tikzDevice.pdf“rel=“noreferer”>its vignette first),其中提供了在R制图中书写LaTeX数学的自然途径。

我还有。见。

另一个例子是:

library(tikzDevice)
library(ggplot2)
tikz( math.tex , standAlone = TRUE, width = 4, height = 4)
qplot(1:10, 1:10, 
  main =  $\mathrm{d} \mathbf{x} = a [\theta - \mathbf{x}] \mathrm{d} t$ )
dev.off()

如果你操作<条码>,可生成:

“latex

Answer 2

你们应该ed问你们的问题,而不是分议(我看一下我可以做些什么)。我有时认为,b 只字面如此深,你需要使用<条码> 替代。这项工作:

 lambda <- 4
 plot(1:10,1:10)

mtext(substitute(paste(d*bolditalic(x)[italic(t)] == 
                       alpha*group("[", (theta - bolditalic(x)[italic(t)] )*d*italic(t) + 
                        lambda, "]") * d * italic(B)[italic(t)] ), list(lambda=lambda)), 
      line=2.25,cex=2)

该机构还同总公司合作,所有权安排更能:

 qplot(1:10, 1:10) + opts(title=substitute(paste(d*bolditalic(x)[italic(t)] == 
                        alpha*(theta - bolditalic(x)[italic(t)] )*d*italic(t) + 
                         lambda * d * italic(B)[italic(t)] ), list(lambda=lambda)), 
                       line=2.25,cex=2)

“entergraph

“d”至少是“总部”,因为我在提及一套网上晚间例子之后理解你的含义:
