1F：→ clansoda: 用readxl读呢? 这个package没这个问题04/12 22:26
用法一样吗？
server = function(input, output){ output$mainPlot = renderPlot({ filename = in
put$file1 # if (is.null(filename)) return(NULL) # temp=read.xlsx(filename$data
path, detectDates = TRUE)
这是xlsx时的写法 请问是直接把read.xlsx改readxl?
2F：→ celestialgod: java装x64还是x86?04/12 23:10
x64
3F：→ celestialgod: 有设定PATH吗04/12 23:11
有设定
4F：推 dreler1: 如果java设定不起来 建议使用readxl 方便很多04/13 03:05
