[R] A tibble with date column appears different in shiny

[Gayathri Nagarajan]

Hi Rui

Tried renderDatatable, but now my shiny UI shows Blank for my tibble. Not
sure what Iam missing suddenly when this was working fine a day back.

The one change I did was:

x <- getURL("
https://raw.githubusercontent.com/nytimes/covid-19-data/master/us-counties.csv
")
us_counties <- read.csv(text = x)

Error in function (type, msg, asError = TRUE)  :
  error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol
version

Hence had to change this to :


  urlfile="
https://raw.githubusercontent.com/nytimes/covid-19-data/master/us-counties.csv
"
  #GN added 3/3
  #GN comment 3/4
  #us_counties<-read_csv(url(urlfile),col_types = list(date = col_date()))
  #GN Add 3/4
  #GN added 3/3
  cols_spec <- cols(
    date = col_date(format = ""),
    county = col_character(),
    state = col_character(),
    fips = col_character(),
    cases = col_double(),
    deaths = col_double()
  )

  us_counties <- read_csv(url(urlfile), col_types = cols_spec)
 ===========================

Gayathri
