以下是带有这些列的数据框

名称（本地数据）

  [1] "Frame"          "Time..Seconds." "X"              "Y"              "Z"              "W"              "X.1"

[106] "Z.32"

我想将所有X，Y，Z列合并在一起。

我可以像这样选择所有X，Y和Z列名称：

Xpos <- c(2, grep(glob2rx("X*"), names(local_data)))

我可以像这样合并这些选定的列：

df.x <- local_data[,Xpos] %>% gather(key, xpox, 2:length(Xpos))

问题是有一些松散的X列没有对应的Y和Z列。例如X.33

我正在寻找一种基于矢量的优雅代码，以标识具有相应Y和X列的X列。从概念上讲，我认为最简单的方法是查找具有相同编号的列，例如X.10，Y.10，Z.10。有提示吗？

谢谢

这是您要搜索的内容吗？我尽力整理一下。

  AbstractSpringSerialPortConnector ard;
    @RequestMapping("/hh")
public void hh() throws NoSuchPortException, TooManyListenersException, IOException {

            ard.connect();
            ard.sendMessage("try");

    }
