问题描述

在我的手机和一台笔记本电脑中使用 DataTables 包在 R 中创建闪亮的应用程序时，我收到了这样的错误.但是，它并没有在其他笔记本电脑上引发错误，相同的代码昨天和前天都在工作.我没有更改代码，但它抛出错误.

I recieved such error when, in created shiny app in R with DataTables packages in my mobile and one laptop. However, it didn't throw error with other laptops, Same code was working yesterday, and day before yesterday. I haven't changed code, but it is throwing error.

为什么某些设备有问题，但不是所有设备都有问题.我使用了其他设备，这些设备没有抛出错误.

Why there is problem with some devices but not all devices. I used other devices, those devices are not throwing error.

推荐答案

我也很痛苦.请查看此 Github 上的问题 #269 的讨论.

I am also suffering. Please take a look at the discussion of this issue #269 on Github.

在 0.1 版之后，您似乎需要使用 as.numeric 来展平"变量，这似乎是一个问题.

It seems to be a problem post version 0.1 where you need to "flatten" variables using as.numeric.

问题

XD-DENG 给出的示例和解决方案是并引用它们:

Example and solution given by XD-DENG was and to quote them:

当我使用时错误消失了

temp <- tapply(iris$Sepal.Length, iris$Species, mean)
  result <- data.frame(species = names(temp),
                       mean = as.numeric(temp))
  return(result)

代替:

temp <- tapply(iris$Sepal.Length, iris$Species, mean)
  result <- data.frame(species = names(temp),
                       mean = temp)
  return(result)

主要区别在于列均值是否有额外的属性、维度.这就是导致错误的原因.

The main difference is whether the column mean has additional attribution, dimension. This is what caused the error.

但鉴于 DT 的 0.1 版在两者上都能完美运行，这仍然很奇怪."

But it's still weird given version 0.1 of DT works perfectly on both."

补丁

@yihui 已将此修复推送到开发版本，因此请尝试更新您的 DT 包.(你可以使用包 devtools 从 github 安装 devtools::install_github('rstudio/DT'))

@yihui has pushed a fix for this to the dev version so please try update your DT package. (You can use package devtools to install from github devtools::install_github('rstudio/DT'))

我希望这能解决这个间歇性错误.

I hope this fixes this intermittent error.
