我对ClickHouse数据库（通过RClickhouse软件包与Rserver连接）运行查询。除非我使用filter函数，否则查询会平稳运行-该函数会生成有关错误对象类型的错误消息
重要信息：仅在公共服务器文件夹中的Rstudio项目中会出现此问题。在与R共享父文件夹（/ users / boris /）的类似项目中，相同的代码可以正常工作（没有错误）
> a <- con %>% tbl("test_sample") %>% select(domain) %>% collect()
> show(a)
# A tibble: 140,000 x 1
domain
* <chr>
1 allforchildren.ru
> a <- con %>% tbl("test_sample") %>% filter(domain == "wildberries.ru") %>% collect()
Error in storage.mode(x) <- "double" :
(list) object cannot be coerced to type 'double'
有人猜测对filter函数做出这种反应的原因是什么？
P.S。会话信息
