我想在jupyter笔记本中使用R.

我去了我的R shell跑了

install.packages(c('rzmq','repr','IRkernel','IRdisplay'),
             repos = c('http://irkernel.github.io/', getOption('repos')))
IRkernel::installspec()

然后我加载了我的ipython笔记本并使用现在可用的R扩展创建了一个新的笔记本.然而,当我访问笔记本时,我遇到了这个内核错误:

Traceback (most recent call last):
  File "C:\Users\Nina Kate\Anaconda3\lib\site-packages\IPython\html\base\handlers.py", line 394, in wrapper
    result = yield gen.maybe_future(method(self, *args, **kwargs))
  File "C:\Users\Nina Kate\Anaconda3\lib\site-packages\IPython\html\services\sessions\handlers.py", line 53, in     post
    model = sm.create_session(path=path, kernel_name=kernel_name)
  File "C:\Users\Nina Kate\Anaconda3\lib\site-packages\IPython\html\services\sessions\sessionmanager.py", line 66, in create_session
    kernel_name=kernel_name)
  File "C:\Users\Nina Kate\Anaconda3\lib\site-packages\IPython\html\services\kernels\kernelmanager.py", line 84, in start_kernel
    kernel_name=kernel_name, **kwargs)
  File "C:\Users\Nina Kate\Anaconda3\lib\site-packages\IPython\kernel\multikernelmanager.py", line 112, in start_kernel
km.start_kernel(**kwargs)

**kw)
  File "C:\Users\Nina Kate\Anaconda3\lib\site-packages\IPython\kernel\manager.py", line 189, in _launch_kernel
return …

我有这样的字符串

x = c(
"blahblah, blah blah, Plate 3, blah blah"
,
"blah blah, blah_Plate 2_blah, blah"
,
"blah, blah, blah blah, blah plate_3"
,
"blah blah, blah, plate 5.txt"
)

我想从所有这些文件名中获取板号,

所以我正在测试我的正则表达式匹配

 gsub("\\<Plate\\>.[0-9]","\\1",workdf_nums_plats$Bioplex_Files)

所以我最终可以做这样的事情

workdf_nums_plats$plat <- ifelse(grepl("\\<Plate\\>.[0-9]", workdf_nums_plats$Bioplex_Files), gsub("\\<Plate\\>.[0-9]","\\1",workdf_nums_plats$Bioplex_Files), NA)

我在返回时返回整个字符串,我尝试使用\ b来设置单词边界,但这没有帮助.

任何建议都会非常感谢!

我正在尝试更新 pgadmin 3 (postgres 9.4) 中的一个表，名为：assay.Luminex.Luminex_GT_shared.Analyte

我不断收到错误：

ERROR:  improper qualified name (too many dotted names): 
assay.luminex.luminex_gt_shared.analyte

我已经测试了反引号和括号无济于事，不断出现语法错误：

SELECT * FROM `assay.Luminex.Luminex_GT_shared.Analyte`;

SELECT * FROM [assay.Luminex.Luminex_GT_shared.Analyte];

我是 SQL 新手，我只是想对表进行简单的更新并陷入困境。
