我是R编程的新手，并开始了一个案例研究，Bellabeat for Google Capstone。我正在访问.csv文件。我尝试了电子表格（太大），SQL（时间戳解析错误），并决定转向R编程来清理和分析。
我似乎无法正确访问我的笔记本电脑驱动器来读取文件。我已经尝试过加载不同的库、包，并尝试了许多不同的语法。我被难倒了，因为这条路对我来说是有意义的，但我总是出错。
工作：安装软件包：

##install.packages("tidyverse")
##install.packages("janitor")
##install.packages("dplyr")
##install.packages("stringr")

##install.packages("Posit.io.R") (not available in my version)

##library(tidyverse)
##library(janitor)
##library(dplyr)
##library(stringr)
##library(readr)
##library(lubridate)

##library(Posit.io.R) (not available)

## Set up working directory to upload csv files.

    ##setwd("C:/Users/Dmanc/OneDrive/Desktop/Google iCloud/Capstone - Study/Bellabeat/Dataset csv files")

## Example:  my_data <- read_csv("my_data.csv")
## Read csv file and output it to new variable file name

    ##dailyActivity <- read_csv("C:/Users/Dmanc/OneDrive/Desktop/Google iCloud/Capstone - Study/Bellabeat/Dataset csv files/dailyActivity_merged.csv")

    ##dailyActivity <- read_csv("C:\Users\Dmanc\OneDrive\Desktop\Google iCloud\Capstone - Study\Bellabeat\Dataset csv files", dailyActivity_merged.csv")
                          
    ##upload_csv("dailyActivity_merged.csv", "dailyActivity")

    ##dailyActivity <- import_csv("dailyActivity_merged.csv")

    ##dir.create("C:/Users/Dmanc/OneDrive/Desktop/Google iCloud/Capstone - Study/Bellabeat/Dataset csv files")

##> dailyActivity <- read_csv("C:/Users/Dmanc/OneDrive/Desktop/Google iCloud/Capstone - ## Study/Bellabeat/Dataset csv files/dailyActivity_merged.csv")
## Error: 'C:/Users/Dmanc/OneDrive/Desktop/Google iCloud/Capstone - Study/Bellabeat/Dataset csv ## files/dailyActivity_merged.csv' does not exist.
