这个错误是因为在执行left_join时,"taskID"这一列在X1_task中的列名为"taskID"(注意这里多了一个不可见字符),因此在连接时无法匹配到正确的列名。可以使用trimws函数去除列名中的不可见字符,或手动修改X1_task的列名,使其与X2_team_leaderboard_info中的列名保持一致。修改后的代码如下:
```
# 去除X1_task中列名的不可见字符
colnames(X1_task) <- trimws(colnames(X1_task))
# 执行left_join
X2_team_leaderboard_info <- X2_team_leaderboard_info %>%
left_join(X1_task, by = "taskID")
```
