通过shiny发布自己的网页APP出现了问题，磨了好几天没找到头绪，希望大家给点建议。
我用Rstudio建立COX回归预测模型app，app在Rstudio中运行是顺利的，发布到shiny.io网站后无无法使用，显示错误信息：
An error has occurred. Check your logs or contact the app author for clarification.
下面是我的COX回归建模代码，和shiny网站logs显示的warning信息。我尝试重新加载了建模所需要的所有R包，多次重启已上传的App，仍未能成功在shiny网站运行自己的网页app，花费了好几天时间，仍找不到头绪，不知道问题出在哪里。特请教各位大神，望各位老师不吝赐教，拜谢，感激涕零。
1、以下是我的构建COX回归模型代码：
library(rsconnect)
library(survival)
library(shiny)
library(DynNom)
library(rms)
subdt <- read.csv("subdt.csv")
dddt <- datadist(subdt)
options(datadist="dddt")
Outcome <- "Surv(Time, Status)"
FinalVariables <- c("Gender","AMB","PCP","Age", "TBIL", "ALB", "BUN", "PCT")
Formula <- formula(paste(paste(Outcome,'~',collapse = ' '),
paste(FinalVariables, collapse = ' + ')))
fcox<-cph(formula = Formula,surv = T, x=T, y=T, data = subdt)
DynNom(fcox,DNtitle="Marneffei Nomogram",DNxlab="Survival Probability",data=subdt,covariate = "numeric")
DNbuilder(fcox,DNtitle="Marneffei Nomogram",DNxlab="Survival Probability",data=subdt,covariate = "numeric")
rsconnect::setAccountInfo(name='guanxxx', #为了保密，部分字母用x代替
token='08A7095E549xxxxxxxxxxxxxxxxx', #为了保密，部分字母用x代替
secret='mWapvwGW1xxxxxxxxxxxxxxxxxxxxxxx') #为了保密，部分字母用x代替
rsconnect::deployApp('DynNomapp')
2、以下是shiny网站logs显示的信息：有一条为Warning: namespace ‘DynNom’ is not available and has been replaced by .GlobalEnv when processing object ‘mlinkF’。（下面已用斜粗体字标显问题行）
