I am trying to import the "Patient Medical Data for Novel Coronavirus COVID-19" dataset from the Wolfram Data Repository, but when I import, it shows me just 427036 results instead of the 692145 shown in the repository (https://datarepository.wolframcloud.com/resources/Patient-Medical-Data-for-Novel-Coronavirus-COVID-19).

I am using the code

ResourceData["Patient Medical Data for Novel Coronavirus COVID-19"]

Can anyone explain to me why Mathematica doesn't import the whole dataset?

After evaluating the ResourceData expression, I get the message:

GlobalDateInterval::shdw: Symbol DateInterval appears in multiple contexts {Global`, System`}; definitions in context Global` may shadow or be shadowed by other definitions.

I get the message only from the first evaluation, if I re-evaluate, I do not see the message.

Perhaps you only get an old datatset?


covid19data =ResourceObject["Epidemic Data for Novel Coronavirus COVID-19"]
DeleteObject[covid19data]; (* otherwise no update *)
covid19data =ResourceObject["Epidemic Data for Novel Coronavirus COVID-19"];
  • $\begingroup$ I tried but it does not work either. I always get the short dataset... $\endgroup$

  • $\begingroup$ @Anto ResourceData[ "Epidemic Data for Novel Coronavirus COVID-19"][Max, \ #ConfirmedCases["LastDate"] &] shows the date of the data. I get DateObject[{2020, 10, 4, 0, 0, 0.}, "Instant", "Gregorian", 2.] $\endgroup$ Oct 6, 2020 at 12:14
  • $\begingroup$ In case it helps: using Ulrich Neumann's three lines I get 846 sets of data in the initial dataset and everything on the Wolfram data repository page seems to work exactly as expected. The data set is number 287.0.0 (37.8Mb). $\endgroup$

    $\begingroup$ What about ResourceUpdate["Patient Medical Data for Novel Coronavirus COVID-19"]. It tells you when you have already downloaded the most recent version. $\endgroup$ Oct 6, 2020 at 17:13
