my head blow up...
I write a simple shinyapp by using DynNom, everything works fine locally; but when it comes to uploading to the shinyapps.io ,it says that:
An error has occurred
the application failed to start (exited with code 1)
Error in value:[[3L]]（cond）:无法改变工作目录
calls：local...tryCatch<-tryCatchList<-tryCatchOne<-Anonymous
停止执行
and this is my code:
library(shiny)
library(DynNom)
library(survival)
rt=read.table("lung(1).txt",sep="",header=T,row.names=1,check.names=F)
rt$sex<-factor(rt$sex,labels=c("male","female"))
fit1 <-coxph(Surv(time, status) ~age+meal.cal+sex+wt.loss,data = rt)
DynNom(fit1,DNxlab = "Survival probability",
KMtitle="Kaplan-Meier plot",
KMxlab = "Time (Days)",
KMylab = "Survival probability")
DNbuilder(fit1)
My dataset(lung(1)) is put in the same file as app.R, this code runs good locally. Hope to get your help!
P.S.
无法改变工作目录：means "Unable to change working directory"
停止执行：means “stop execution”
