r - as.character(as.Date()) returns NA in shiny datatable -

-

the following code works in datatable display:

observe({ if (!any(input$date == "na")) {   dates <- isolate(as.date(dataset$data[, input$date], format = input$dateformat)) }  if (!any(input$date == "na")) {   dataset$data[, input$date] <- dates }

however, dataset$date (date column) saved in date format. want save in character format. here's attempt:

observe({ if (!any(input$date == "na")) {   dates <- isolate(as.date(dataset$data[, input$date], format = input$dateformat)) }  if (!any(input$date == "na")) {   dataset$data[, input$date] <- as.character(dates) }

this gives me na values date column. thoughts on how fix appreciated.

p.s. i'm not sure if isolate needed in case, latest attempt, i've tried different versions such basic as.character(as.date())
