gWidgets-ginput()函数错误 [英] gWidgets - ginput() function error

问题描述

从gWidgets启动ginput弹出窗口时遇到问题.

I'm having a problem with launching the ginput pop-up from gWidgets.

这是错误:

正在加载所需的软件包:gWidgetstcltk (函数(类，fdef，mtable)中的错误: 找不到签名"guiWidgetsToolkittcltk""的函数".ginput"的继承方法 另外:警告消息: 在库中(包，lib.loc = lib.loc，character.only = TRUE，logical.return = TRUE，: 没有名为"gWidgetstcltk"的软件包

Loading required package: gWidgetstcltk Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘.ginput’ for signature ‘"guiWidgetsToolkittcltk"’ In addition: Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, : there is no package called ‘gWidgetstcltk’

我使用弹出窗口键入一个数字，然后将其分配给变量.

I use the popup to type a number that I then assign to a variable.

代码段如下:

options(guiToolkit = "tcltk") # Tool kit dependency for gwidgets.
library(gWidgets) # Package required to launch ginput gui.

width.var <- as.numeric(ginput("Enter value for - Width        ",
                               title = "PNG dimensions", 
                               icon = "info"))

补充信息:

我将我的R版本从3.2.5更新到了3.4.1，并安装了最新的RStudio版本.我已经在R3.4.1上运行了此代码部分，但是在另一台计算机上没有任何问题.

I updated my R version from 3.2.5 to 3.4.1 as well as installing the latest RStudio version. I've run this code section before on R3.4.1 but on a different computer without any issues.

现在我怀疑它是RStudio，但我不知道如何解决它.

Right now i suspect it's RStudio but i don't know how to fix it.

非常感谢您的帮助.

答案:

该错误使我有些困惑，看起来比实际情况还要复杂.

The error threw me a bit and looks more complicated than it really is.

我通过简单地安装"gWidgetstcltk"来修复.我以为是因为我分别加载了tcltk和gWidgets就足够了.谢谢亚历克斯

I fixed by simply installing "gWidgetstcltk". I assumed that because I load tcltk and gWidgets separately that it would be enough. Thanks Alex
