→ clansoda: 用readxl讀呢? 這個package沒這個問題04/12 22:26
用法一樣嗎?
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)
這是xlsx時的寫法 請問是直接把read.xlsx改readxl?
→ celestialgod: java裝x64還是x86?04/12 23:10
x64
→ celestialgod: 有設定PATH嗎04/12 23:11

推 dreler1: 如果java設定不起來 建議使用readxl 方便很多04/13 03:05
