在 R MarkDown 中使用 RHRV 包加载心率数据时出现问题

Question

我在使用

.txt

包中的

LoadBeatAscii()

函数在 R Markdown 中加载

RHRV

文件时遇到问题。当我尝试从文件夹加载时，它显示：

setwd(RecordPath) 中的错误：无法更改工作目录

示例

library(RHRV) 
hrv.data <- CreateHRVData() #This creates an empty list.object in which to load raw data into
hrv.data <- SetVerbose(hrv.data, TRUE) #to return additional information 
hrv.data <- LoadBeatAscii(hrv.data, RecordName = "beat_ascii.txt", RecordPath = "Data/beat_ascii.txt") #loading data from 'Data' folder into the hrv.data list object

我在本示例中使用的数据可从 milegroup（它是包含节拍位置的 ascii 文件）在线获取，称为

beat_ascii.txt

，可在此处获取：http://milegroup.github.io/ghrv/packages.html

否则这里有一小部分数据样本：

)

有人明白问题出在哪里吗？

更新 其他人也遇到了同样的问题here但没有解决方案。

Answer 1

错误命名为

.txt

文件，应从

RecordPath

中省略：

hrv.data <- LoadBeatAscii(hrv.data, RecordName = "beat_ascii.txt", RecordPath = "C:/Users/Username/Desktop/Desktop/Data")
