尝试将摘要保存在文件中时，出现“无法强制将类“c(“summary.turnpoints”、“turnpoints”)”转换为 data.frame”错误。我试图用 as.data.frame 解决这个问题，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$A)
print(data.tp)
转折点：data$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)

data.sum=summary(data.tp)

write.table(data.sum, file = "C:\\Users\\Ron\\Desktop\\datasetTurnP.txt")
Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) :

In addition: Warning messages:

2: package ‘pastecs’ was built under R version 3.0.1
如何将这些摘要结果保存到文本文件中？
谢谢你。
