This instrument is the preferred choice for many Brookfield customers.
RHEOCALC T PROGRAM PRO
When controlled by PC, the DV-II+ PRO becomes a Rheometer with variable speed capability from 0.01 to 200 rpm. For more information on SQL engines, see this page on knitr language engines.The DV-II+ PRO Digital Viscometer combines traditional Brookfield accuracy, reliability and versatility with the advantages of continuous sensing, temperature measurement and data output to PC or printer.
RHEOCALC T PROGRAM CODE
Another benefit is that the SQL code in a code chunk is highlighted, making it very easy to read. If you are using the proverbial spaghetti code that is hundreds of lines long, then a SQL code chunk might be a good option. For example, you do not have to escape quotes. The benefits to using SQL in a code chunk are that you can paste your SQL code without any modification. Ggplot(mydataframe, aes(total, subscribe, color = year)) + SELECT "month_idx", "year", "month", SUM(CASE WHEN ("term_deposit" = 'yes') THEN (1.0) ELSE (0.0) END) AS "subscribe", An earlier blog post discussed our vision.ĭid you know that you can run SQL code in an R Notebook code chunk? To use SQL, open an R Notebook in the RStudio IDE under the File > New File menu. Using databases with R is a broad subject and there is more work to be done.
RHEOCALC T PROGRAM DRIVERS
If you are using open-source tools, you can bring your own driver or use community packages – many open-source drivers and community packages exist for connecting to a variety of databases. The examples below use the Oracle ODBC driver. If you are using RStudio Desktop Pro or other RStudio professional products, you can download RStudio Professional Drivers for no additional cost on the same machine where these products are installed. These new features are extensible and will work with any R package that has a connections contract. The IDE has a wizard for setting up new connections, and a tab for exploring established connections. With the latest versions of the RStudio IDE, you can connect to, explore, and view data in a variety of databases. RStudio also made recent improvements to its products so they work better with databases. The odbc R package is DBI-compliant, and is recommended for ODBC connections. The odbc R package provides a standard way for you to connect to any database as long as you have an ODBC driver installed. As of this writing, SQL variants are supported for the following databases: Oracle, Microsoft SQL Server, PostgreSQL, Amazon Redshift, Apache Hive, and Apache Impala. The dplyr package now has a generalized SQL backend for talking to databases, and the new dbplyr package translates R code into database-specific variants. When working with databases, you should always use packages that are DBI-compliant. The DBI specification has gone through many recent improvements. The query examples below demonstrate some of the capabilities of these R packages. Several recent package improvements make it easier for you to use databases with R.
