In today's fast-paced world, there are tremendous amount of data being recorded periodically. These data may come from sensors which record some measurement along with some categorization such as time and sensor type.
To make sense of such data, most data analysts use the R programming language as a tool. Apart from being free, there are many nice features of R which can help make my data analysis work easier.
This post records the use of the
aggregate function in R which I often use to create meaning out of the humongous data which I lay my hands on.
There is a number dial that changes rapidly and a text field for the user to enter his name. When the user clicks on the "get lucky number" button, jQuery is used to send the lucky number on the number dial and the user name to the server.
The server generates a text file based on the input from the user and sends the file back to the browser. The browser will then show a download dialog box for the user to decide whether to save a copy of the file or view the file using one of the native applications found in his/her computer.
