尝试将摘要保存在文件中时,我有一个“无法强制类”c(“summary.turnpoints”,“turnpoints”)“to data.frame”错误。我试图用as.data.frame修复它,但没有成功。
代码:
library(plyr)
library(pastecs)
data <- read.table("C:\\Users\\Ron\\Desktop\\dataset.txt", header=F, col.name="A")
data.tp=turnpoints(data$A)
print(data.tp)
转折点:数据$ A
nbr observations : 5990
nbr ex-aequos : 51
nbr turning points: 413 (first point is a pit)
E(p) = 3992 Var(p) = 1064.567 (theoretical)

In addition: Warning messages:

如何将这些摘要结果保存到文本文件?
谢谢。
答案 0 :(得分:3)
查看以下的值部分:
?pastecs::summary.turnpoints
应该清楚的是,这不是一组列表,所有列表都具有相同的长度。因此错误消息。所以,而不是要求不可能,...告诉我们你想要保存什么。
实际上并非不可能,只有write.table
无法实现,因为它不是数据帧。 dump
函数允许您构造该摘要对象的structure(...)
表示的ASCII表示。
dump(data.sum, file="dump_data_sum.asc")
这可能是source()-ed
