### Remove "bad" data
The dataframe includes a few hundred entries when bikes were taken out of docks and checked for quality by Cyclistic or ride_length was negative We will create a new version of the dataframe (v2) since data is being removed

我該如何糾正這個
我已嘗試檢查其他站點以了解此錯誤的性質，但收效甚微。
有兩個錯誤導致 OP 底部的代碼塊失敗。
首先，將trip_length轉換為數字的代碼部分由於拼寫錯誤而產生錯誤， r convert-to-numeric以rconvert 。
```{rconvert to numeric}
all_trips <- all_trips %>%
mutate(ride_length = as.numeric(ride_length))
is.numeric(all_trips$ride_length)
```
Knitr 只是跳過代碼塊，因為它不識別rconvert引擎。
這隱藏了另一個錯誤，即在輸入的 Kaggle 數據集中沒有列ride_length 。 由於這個微妙之處，第 155 行的代碼失敗，因為all_trips$ride_length不存在。
要糾正錯誤，我們需要做兩件事。 首先，回到r create new columns代碼塊中，我們添加一行代碼來計算trip_length 。
all_trips$ride_length <- all_trips$ended_at - all_trips$started_at
其次，我從 Kaggle.com 下載的數據使用start_station_name和end_station_name ，這顯然與 OP 中使用的數據不同。 行程開始和結束時間在我下載的數據中也被稱為started_at和ended_at 。
因此，我們需要將選擇無效行程的行更改為以下內容：
all_trips_v2 <- all_trips[!(all_trips$start_station_name == "HQ QR" | all_trips$ride_length<0), ]
通過這些更正，最小可重現示例將正確呈現 output。 我們打印渲染文件的最后一部分，以證明它的渲染沒有錯誤。
OP 發布的整個腳本的更正版本如下所示：

### Inspecting the column names
```{r inspecting-column-names}
#colnames(dec_2021)
#colnames(jan_2022)
#colnames(feb_2022)
#colnames(mar_2022)

#colnames(aug_2022)
#colnames(sep_2022)
#colnames(oct_2022)
#colnames(nov_2022)
```
### Stack individual quarter's data frames into one big data frame
```{r merge-dataframes}
# all_trips <- bind_rows(dec_2021, jan_2022, feb_2022, mar_2022, apr_2022, may_2022, jun_2022, jul_2022, aug_2022, sep_2022, oct_2022, nov_2022)
```
```{r create-new-columns}
# all_trips$date <- as.Date(all_trips$start_time) #The default format is yyyy-mm-dd
all_trips$date <- as.Date(all_trips$started_at)
all_trips$month <- format(as.Date(all_trips$date), "%m")
all_trips$day <- format(as.Date(all_trips$date), "%d")
all_trips$year <- format(as.Date(all_trips$date), "%Y")
all_trips$day_of_week <- format(as.Date(all_trips$date), "%A")
all_trips$ride_length <- all_trips$ended_at - all_trips$started_at #added
```
### Convert "ride_length" from Factor to numeric so we can run calculations on the data
```{r convert-to-numeric}
all_trips <- all_trips %>%
mutate(ride_length = as.numeric(ride_length))
is.numeric(all_trips$ride_length)
```
### Remove "bad" data
The dataframe includes a few hundred entries when bikes were taken out of docks and checked for quality by Cyclistic or ride_length was negative We will create a new version of the dataframe (v2) since data is being removed
```{r remove-bad-data}
#all_trips_v2 <- all_trips[!(all_trips$from_station_name == "HQ QR" | all_trips$ride_length<0), ]
all_trips_v2 <- all_trips[!(all_trips$start_station_name == "HQ QR" | all_trips$ride_length<0), ]
```
### View the cleaned dataset
Note: because `View()` requires a graphical user interface, we can't use it when knitting an R Markdown file.
```{r view-dataset}
# View(all_trips_v2)
```
## Conduct descriptive analysis
### Descriptive analysis on ride_length (all figures in seconds)
```{r quick-summary-ride-length}
summary(all_trips_v2$ride_length)
```
### Compare members and casual users
In this section, we needed to change `usertype` to `member_casual` based on data from Kaggle.
```{r compare-casual-and-members-ride-length}
aggregate(all_trips_v2$ride_length ~ all_trips_v2$member_casual, FUN = mean)
aggregate(all_trips_v2$ride_length ~ all_trips_v2$member_casual, FUN = median)
aggregate(all_trips_v2$ride_length ~ all_trips_v2$member_casual, FUN = max)
aggregate(all_trips_v2$ride_length ~ all_trips_v2$member_casual, FUN = min)
```
### The average ride time by each day for members vs casual users
```{r average-ride-time-of-users}
aggregate(all_trips_v2$ride_length ~ all_trips_v2$member_casual + all_trips_v2$day_of_week, FUN = mean)
```
### Notice that the days of the week are out of order. Let's fix that.
```{r correct-the-days-of-the-week}
all_trips_v2$day_of_week <- ordered(all_trips_v2$day_of_week, levels=c("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"))
```
### Now, let's run the average ride time by each day for members vs casual users
```{r average-ride-duration-of-users}
aggregate(all_trips_v2$ride_length ~ all_trips_v2$member_casual + all_trips_v2$day_of_week, FUN = mean)
```
### analyze ridership data by type and weekday
Changed `start_time` to `started_at` based on data received from Kaggle.com.
```{r analyze-ride-data-by-type-and-weekday}
plot1 <- all_trips_v2 %>%
mutate(weekday = wday(started_at, label = TRUE)) %>% #creates weekday field using wday()
group_by(member_casual, weekday) %>% #groups by usertype and weekday
summarise(number_of_rides = n() #calculates the number of rides and average duration
,average_duration = mean(ride_length)) %>% # calculates the average duration
arrange(member_casual, weekday) %>% # sorts
drop_na()
```
