我在我的Mountain Lion Mac上安装了R3.0,经过一些试验和错误后,http ://r.research.att.com/为R3.0:GTK + 2.24.17框架提出了GTK版本.
我将软件包加载到R3.0并运行其中一个演示.我看到(暂时)生成了一个图形,但是R立刻崩溃了.通常情况下,当我运行"win $ showAll()"行时会发生崩溃(CairoDevice工作没问题).这是生成错误日志的开始(包含我的配置的详细信息).谢谢!

Exception …我正在尝试根据纽约犯罪历史数据制作一个闪亮的应用程序。我正在使用单个闪亮页面方法。这是数据： https //data.world/data-society/nyc-crime-data
出于某种原因，当我选择年份来输出犯罪统计数据时，我的输出仅在 RStudio 的查看器中输出，而不是在 Shiny 弹出窗口的主面板上。这是完整的代码：

如何在不使用引号的情况下告诉解释器将矢量内容读取为字符串？例子：
vector<-c("AAA", "BBB", "CCC", "DDD", "EEE", "FFF", "GGG", "HHH")
vector
[1] "AAA" "BBB" "CCC" "DDD" "EEE" "FFF" "GGG" "HHH"
如果我想用以下方法构建相同的对象怎么办：
vector<-c(AAA, BBB, CCC, DDD, EEE, FFF, GGG, HHH)
Error: object 'AAA' not found
我们有像“to.character”这样的函数吗？这对我有很大帮助。提前致谢，对于幼稚的问题很抱歉。
