我一直试图在R笔记本中拍摄错误,其中R块正确执行,但是当我尝试预览笔记本时,出现以下错误:
创建笔记本时出错:值必须为3,但是FUN(X [[1]])结果为1。请参见第31行。
造成错误的代码是我的数据的弗里德曼分析(使用agricolae
包)。
这是正确执行的块,并且用于Friedman分析(这些是我的R笔记本中的代码块,但是出于以下目的,我省略了笔记本中所需的{r}
和回勾号)这个问题):
if(!require(agricolae))
{
print("You are missing the package 'agricolae', we will now try to install it...")
install.packages("agricolae")
library(agricolae)
}
WineTasting <- data.frame(
Taste = c(5.40, 5.50, 5.55,
5.85, 5.70, 5.75,
5.20, 5.60, 5.50,
5.55, 5.50, 5.40,
5.90, 5.85, 5.70,
5.45, 5.55, 5.60,
5.40, 5.40, 5.35,
5.45, 5.50, 5.35,
5.25, 5.15, 5.00,
5.85, 5.80, 5.70,
5.25, 5.20, 5.10,
5.65, 5.55, 5.45,
5.60, 5.35, 5.45,
5.05, 5.00, 4.95,
5.50, 5.50, 5.40,
5.45, 5.55, 5.50,
5.55, 5.55, 5.35,
5.45, 5.50, 5.55,
5.50, 5.45, 5.25,
5.65, 5.60, 5.40,
5.70, 5.65, 5.55,
6.30, 6.30, 6.25),
Wine = factor(rep(c("Wine A", "Wine B", "Wine C"), 22)),
Taster = factor(rep(1:22, rep(3, 22))))
head(WineTasting)
这是错误所在:
Friedmantest <- with(WineTasting,friedman(Taster,Wine,Taste,alpha=0.05, group=TRUE,console=TRUE))
Friedmantest
代码可以正常工作,并将正确的结果打印到控制台,但是无法在笔记本中预览,从而产生错误。
我尝试使用不同的数据集运行此操作,但无济于事(出现相同的错误消息)。 Google并没有真正产生任何有用的结果,而且以前在Stackoverflow中似乎没有讨论过此错误。任何帮助将不胜感激。
library(agricolae)
WineTasting <- data.frame(
Taste = c(5.40, 5.50, 5.55,
5.85, 5.70, 5.75,
5.20, 5.60, 5.50,
5.55, 5.50, 5.40,
5.90, 5.85, 5.70,
5.45, 5.55, 5.60,
5.40, 5.40, 5.35,
5.45, 5.50, 5.35,
5.25, 5.15, 5.00,
5.85, 5.80, 5.70,
5.25, 5.20, 5.10,
5.65, 5.55, 5.45,
5.60, 5.35, 5.45,
5.05, 5.00, 4.95,
5.50, 5.50, 5.40,
5.45, 5.55, 5.50,
5.55, 5.55, 5.35,
5.45, 5.50, 5.55,
5.50, 5.45, 5.25,
5.65, 5.60, 5.40,
5.70, 5.65, 5.55,
6.30, 6.30, 6.25),
Wine = factor(rep(c("Wine A", "Wine B", "Wine C"), 22)),
Taster = factor(rep(1:22, rep(3, 22))))
Friedmantest <- with(WineTasting,friedman(Taster,Wine,Taste,alpha=0.05, group=TRUE,console=TRUE))
答案 0 :(得分:0)
为使其正常工作,我删除了console=TRUE
参数,并添加了print(Friedmantest)
语句。现在,笔记本预览会打印Friedman测试的输出。现在正确的代码如下所示:
Friedmantest <- with(WineTasting,friedman(Taster,Wine,Taste,alpha=0.05, group=TRUE))
print(Friedmantest)
