ggplot(iris[iris$Species == "setosa",],aes(Sepal.Width)) + geom_density() Here, we are subsetting the dataframe before passing it to ggplot. It is a very useful tool derived from the data frame data structure. To make the code more readable, one can also use dplyr's filter: libr...

When testing with Google App Engine's testing library the challenges of eventual consistency are present in the same manner they will be in production. Therefore in order to write something into the datastore to test retrieval you have to create a context which is strongly consistent. type Foo str...

This example shows how to find circular blobs in an grayscale image. The evaluation of the circularity of a blob is done using the area and the perimeter (arc length) of the contour. The center point gets evaluated using the moments of the contour. #include "opencv/cv.h" #include &quot...

When the temp table is created by itself, it will remain while the connection is open. // Widget has WidgetId, Name, and Quantity properties public async Task PurchaseWidgets(IEnumerable<Widget> widgets) { using(var conn = new SqlConnection("{connection string}")) { ...

The simplest way to wrap and access a piece of state is Agent. The module allows one to spawn a process that keeps an arbitrary data structure and allows one to send messages to read and update that structure. Thanks to this the access to the structure is automatically serialized, as the process onl...
