You’ll need two packages to get started, so install them before doing anything else:

Introduction to SQL: 5 Key Concepts Every Data Professional Must Know.But how can we connect to it from R and R Shiny? That’s what we’ll answer next.Īre you a bit rusty with SQL? Use the following articles as a refresher: To conclude – we now have the dataset loaded into the Postgres database.

Looking for a career switch? Here’s how to start a career as an R Shiny developer. You can Google the installation steps – it shouldn’t take more than a couple of minutes. Installation is OS-specific, so we won’t go through that today. We assume you already have the Postgres database installed, as well as a GUI management tool like pgAdmin. There’s no better way to learn than through a hands-on example, so you’ll also create a fully-working interactive dashboard with R Shiny. Today you’ll learn how to connect R and R Shiny to the Postgres database – one of the most well-known open-source databases. As a data professional, you must know how to connect to different databases through different programming languages. That doesn’t mean it’s the right thing to do, as most production environments have data stored in one or multiple databases. It’s always easier to read and write to local CSV files. =CONCATENATE('INSERT INTO linestringtest VALUES(' A1 ', ST_GeomFromText('' B1 '', 4326), to_date('' TEXT(C1 'dd.mm.yyyy hh:m') '', 'DD.MM.YYYY HH24:MI'), to_date('' TEXT(D1 'dd.mm.yyyy hh:m') '', 'DD.MM.Managing database connections can be messy at times. If you need to assign coordinate system to geometry than you need second argument in function ST_GeomFromText, e.g.

This formula would generate SQL which you can paste into pgAdmin SQL console and execute statements. Then in some column after D you paste formula and copy/paste in each row: =CONCATENATE('INSERT INTO linestringtest VALUES(' A1 ', ST_GeomFromText('' B1 ''), to_date('' TEXT(C1 'dd.mm.yyyy hh:m') '', 'DD.MM.YYYY HH24:MI'), to_date('' TEXT(D1 'dd.mm.yyyy hh:m') '', 'DD.MM.YYYY HH24:MI') ') In that way excel automatically puts data into separate columns. Your separators in CSV file should be semi-colon ( ). I'll describe procedure for Microsoft Office but it should be very similar also to do it in Libre Office. If you have Microsoft Excel or LibreOffice you could open your csv file in one of these applications.
