I am trying to obtain COVID deaths for each county in the US by race and ethnicity. However, the North Carolina website does not have an option to download a .CSV file and instead houses their data in Tableau data visualizations. Any help on how to transform information in the data visualizations into an R data table would be appreciated. I need the data for every county in the state. I have tried looking at other posts on this site but haven't been able to figure them out on my own.

Thank you.
everyone!
I'm doing research using COVID 19 Tweets. I've downloaded some COVID 19-sourced tweets from https:/zenodo.org/record/3970127#.Xy12rChKiUk. However, the data only includes the Twitter ID. Does anyone know how to hydrate the data in RStudio and get the JSON file with the text? It seems I can use the Twarc
package, but I'd like to do the whole process in the R environment, not in Python.
I realize this is a tad late but here goes: Twarc's package description includes a mention of a similar package for R--which would answer OP's question.
"For R there is academictwitteR. Unlike twarc, it focuses solely on querying the Twitter Academic Research Product Track v2 API endpoint. Data gathered in twarc can be imported into R for analysis as a dataframe if you export the data into CSV using twarc-csv."
Here is the source.
When following youtube of vamsidhar ambatipudi on Mktg analytics tutorial videos I found a few data sets which could not be tested on R 3.6,it said such data not available in 3.6,his was on R 3.2.How can I work on such Datasets in R. For example Storesales dataset, National football league, Internet sales, used cars etc. Pls help.
I am new to R and have just started to use it. I am currently experimenting with the quantmod, rugarch and rmgarch packages.
In particular, I'm implementing the last package to make a multivariate portfolio analysis for the case of the european markets. In this sense, I need to download the 3-month german treasury bills, in order to use them as risk free rate. However, as far as I known, I can´t download the the mentioned data serie from Yahoo, Google or FDRA databases, so I have already downloaded them from investing.com and I want to load them in R.
The fact here is, my data is different from the ones downloaded by the getsymbols () function of yahoo, because in this case I only have 2 columns, the date column and the closing price column. To sump up, the question arises here is, is there any way to load this type of data in R for rmgarch purposes??
thanks in advance
Not sure if this is the issue, but this is how you might go about getting the data from a csv file.
data <- read.csv(file="file/path/data.csv")
head(data) # Take a look at your data
# Do this if you want the data only replacing ColumnName with the proper name
data_only <- data$ColumnName
It looks like the input data for rugarch needs to be an xts vector. So, you might want to take a look at this. You might also want to take a look at ?read.csv.

What datasets exist out on the internet that I can run statistical analysis on?
The datasets package is included with base R. Run this command to see a full list:
library(help="datasets")
Beyond that, there are many packages that can pull data, and many others that contain important data. Of these, you may want to start by looking at the HistData package, which "provides a collection of small data sets that are interesting and important in the history of statistics and data visualization".
For financial data, the quantmod package provides a common interface for pulling time series data from google, yahoo, FRED, and others:
library(quantmod)
getSymbols("YHOO",src="google") # from google finance
getSymbols("GOOG",src="yahoo") # from yahoo finance
getSymbols("DEXUSJP",src="FRED") # FX rates from FRED
FRED (the Federal Reserve of St. Louis) is really a landmine of free economic data.
Many R packages come bundled with data that is specific to their goal. So if you're interested in genetics, multilevel models, etc., the relevant packages will frequently have the canonical example for that analysis. Also, the book packages typically ship with the data needed to reproduce all the examples.
Here are some examples of relevant packages:
alr3: includes data to accompany Applied Linear Regression (http://www.stat.umn.edu/alr)
arm: includes some of the data from Gelman's "Data Analysis Using Regression and Multilevel/Hierarchical Models" (the rest of the data and code is on the book's website)
BaM: includes data from "Bayesian Methods: A Social and Behavioral Sciences Approach"
BayesDA: includes data from Gelman's "Bayesian Data Analysis"
cat: includes data for analysis of categorical-variable datasets
cimis: from retrieving data from CIMIS, the California Irrigation Management Information System
cshapes: includes GIS data boundaries and data
ecdat: data sets for econometrics
ElemStatLearn: includes data from "The Elements of Statistical Learning, Data Mining, Inference, and Prediction"
emdbook: data from "Ecological Models and Data"
Fahrmeir: data from the book "Multivariate Statistical Modelling Based on Generalized Linear Models"
fEcoFin: "Economic and Financial Data Sets" for Rmetrics
fds: functional data sets
fma: data sets from "Forecasting: methods and applications"
gamair: data for "Generalized Additive Models: An Introduction with R"
geomapdata: data for topographic and Geologic Mapping
nutshell: contains all the data from the "R in a Nutshell" book
nytR: provides access to congressional vote data through the NY Times API
openintro: data from the book
primer: includes data for "A Primer of Ecology with R"
qtlbook: includes data for the R/qtl book
RGraphics: includes data from the "R Graphics" book
Read.isi: access to old World Fertility Survey data
A broad selection on the Web. For instance, here's a massive directory of sports databases (all providing the data free of charge, at least that's my experience). In that directory is databaseBaseball.com, which contains among other things, complete datasets for every player who has ever played professional baseball since about 1915.
StatLib is an other excellent resource--beautifully convenient. This single web page lists 4-5 line summaries of over a hundred databases, all of which are available in flat-file form just by clicking the 'Table' link at the beginning of each data set summary.
The base distribution of R comes pre-packaged with a large and varied collection of datasts (122 in R 2.10). To get a list of them (as well as a one-line description):
data(package="datasets")
Likewise, most packages come with several data sets (sometimes a lot more). You can see those the same way:
data(package="latticeExtra")
data(package="vcd")
These data sets are the ones mentioned in the package manuals and vignettes for a given package, and used to illustrate the package features.
A few R packages with a lot of datasets (which again are easy to scan so you can choose what's interesting to you): AER, DAAG, and vcd.
Another thing i find so impressive about R is its I/O. Suppose you want to get some very specific financial data via the yahoo finance API. Let's say closing open and closing price of S&P 500 for every month from 2001 to 2009, just do this:
tick_data = read.csv(paste("http://ichart.finance.yahoo.com/table.csv?",
"s=%5EGSPC&a=03&b=1&c=2001&d=03&e=1&f=2009&g=m&ignore=.csv"))
In this one line of code, R has fetched the tick data, shaped it to a dataframe and bound it to 'tick_data' all . (Here's a handy cheat sheet w/ the Yahoo Finance API symbols used to build the URLs as above)

Obviously UK based data, but that shouldn't matter. Covers everything from abandoned cars to school absenteeism to agricultural price indexes
Have you considered Stack Overflow Data Dumps?
You are already familiar with what the data represents i.e. the business logic it tracks
A good start to look for economic data are always the following three addresses:
World Bank - Research Datasets
IMF - Data and Statistics
National Bureau of Economic Research
A nice summary of dataset links for development economists can be found at:
Devecondata
Edit:
The World Bank decided last week to open up a lot of its previously non-free datasets and published them online on its revised homepage. The new internet appearance looks pretty nice as well.
The World Bank - Open Data
Another good site is UN Data.
The United Nations Statistics Division
(UNSD) of the Department of Economic
and Social Affairs (DESA) launched a
new internet based data service for
the global user community. It brings
UN statistical databases within easy
reach of users through a single entry
point (http://data.un.org/). Users can
now search and download a variety of
statistical resources of the UN
system.
http://www.data.gov/ probably has something you can use.
In their catalog of raw data you can set your criteria for the data and find what you're looking for http://www.data.gov/catalog/raw
A bundle of 268 small text files (the worked examples of "The R Book") can be found in The R Book's companion website.
