本文介绍了如何在for循环中使用tapply()并在R中打印输出?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 $ b Myrepfun< - function(x,n) { nstudents< - replicate(1000,sum(sample(x,size = n,replace = TRUE))) quantile(nstudents,probs = 0.95) tapply(weight,schoolcode,Myrepfun,n = 2) 我想用这在for循环内并打印出输出。我已经尝试了以下,并得到错误消息:错误:意外符号在for(n 12:13)(t = tapply(ow,sc,ndropfunction,n,p = 0.95)output for(n in 1:25){t = tapply(weight,schoolcode,Myrepfun, n,p = 0.95)print(c =(t,n))} 解决方案 可复制的例子使世界去但是,你的问题是你的代码在语法上是不合法的,如果你想把所有东西放在一行上,你需要用分号分隔这些命令:; 或者把它们放在两行不同的行上,两个例子: $ $ p $ > x #----- [1] 0.4958944 1.0000000 [1] 0.4958944 2.0000000 [1] 0.4958944 3.0000000 $ b $ gt; for(i in 1:3){ + out + print(c(out,i )) +} #----- [1] 0.4958944 1.0000000 [1] 0.4958944 2.0000000 [1] 0.4958944 3.0000000 I am using tapply() to apply a function to my dataMyrepfun <- function(x,n){ nstudents <- replicate(1000,sum(sample(x, size=n,replace=TRUE))) quantile(nstudents,probs=0.95)}tapply(weight,schoolcode,Myrepfun,n=2)I would like to use this within a for loop and print out the output. I have tried the following and I get the error message: Error: unexpected symbol in "for(n in 12:13) (t=tapply(ow,sc,ndropfunction,n,p=0.95) outputfor(n in 1:25) {t=tapply(weight,schoolcode,Myrepfun,n,p=0.95) print(c=(t,n))} 解决方案 Reproducible examples make the world go round. However, your problem is that your code is not syntactically valid. If you want to put everything on a single line, you need to separate the commands by a semicolon: ;. Or, put them on two different lines. Two examples:> x <- runif(100)> for (i in 1:3){out <- mean(x);print(c(out,i))}#-----[1] 0.4958944 1.0000000[1] 0.4958944 2.0000000[1] 0.4958944 3.0000000> for (i in 1:3){+ out <- mean(x)+ print(c(out,i))+ }#-----[1] 0.4958944 1.0000000[1] 0.4958944 2.0000000[1] 0.4958944 3.0000000 这篇关于如何在for循环中使用tapply()并在R中打印输出?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 10-12 10:54
