1. esProc’s function options
Many functions in esProc can use function options with which the same function can have different work patterns. The basic format of function options is f@o(…) in which o is f function’s option. For example:

To make data analysis, first you need to load the original data. The data used most frequently comes from the text files or the databases. In esProc, you can load data from the text files or the databases easily and quickly.
1. Text file data
esProc can loaddata from a text file as a table sequence. For example, the te...

In esProc computing, we use constants frequently or sometimes store the data in the cellset directly. In this article, let’s learn the usage of constants in the esProc.
1. Directly using constant in the expressions
Constants can be directly used in the esProc expressions:
