在R语言中、概率函数的语法形式为:[dpqr]distribution_abbreviation() 其中方框号中的dpqr是函数的第一个字母,分别代表:d = density:密度函数;p = distribution function:分布函数;q = quantile function:分位数函数;r = random generation (random deviates):使用对应概率分布生成随机值函数; 以正太分布为例:正太...

R-森林图(Forest Plot)绘制方法 使用R绘制森林图(Forest Plot)的方法比较多,这里重点介绍R-forestplot包和R-ggforestplot包绘制。 「注意」:安装R-ggforestplot包之前,确保broom包已安装,否则可能会安装出错。 R-forestplot包绘制 这一部分我们直接使用提供的数据进行绘制,重点在于展示forestplot包中一些绘图参数的设置。
function f = onehump(x) r = x(1)^2 + x(2)^2; s = exp(-r); f = x(1)*s+r/20; end This code creates the myplot helper function. Get function stop = myplot(x,optimValues,state) stop = false; switch state case 'init' % Setup for plots or dialog boxes hold on case '...

我们还可以进一步的看一下为何这个映射是经过I函数处理的,原因在enrichplot:::cnetplot.enrichResult的源码中,这里需要对S3对象有一定的了解,以前的R tips中推文有专门说过如何真正的获取一个R函数的源码。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 enrichplot:::cnetplot.enrichResult # function (x, ...
