shiny-seq 复现

之前的 倒在boxplot前的失败经验
终于搞定了如何用 raw data (一个表达矩阵，一个有两种分组信息的annotation file) 画出 boxplot 和 PCA. 反正作者代码一环套一环是看不懂的 (:з)∠)
ui:
ui <- navbarPage(title = "ShinySeq - Data to Plots",
#### Raw Data ####

accept = c('text/csv',
'text/comma-separated-values',

fileInput("file2","Choose annotation file to upload",

ps. 某两个嵌套for循环就已经耗尽了全部力气，但突然领悟了 reactiveValues 的真实方便

发现一个看起来很高级的做过场渲染的包，waiter https://github.com/JohnCoene/waiter 试图使用失败
目前完成到了……这样
画不出和作者一样的图只是因为没设置ylim, 毕竟 raw data 就是 raw data, 动是动不起的
3D PCA hmmmm 画出来都得插会儿腰
