## SAS Packages:
|
|
To get started with SAS Packages try this [**`Getting Started with SAS Packages`**](https://github.com/yabwon/SAS_PACKAGES/blob/master/SPF/Documentation/Getting_Started_with_SAS_Packages.pdf "Getting Started with SAS Packages") presentation (see the `./SPF/Documentation` directory).
|
|
|
|
## Available packages:
|
|
Currently the following packages are available:
|
|
|
|
---
|
|
|
|
- **SQLinDS**\[2.2\], based on Mike Rhoads' article *Use the Full Power of SAS in Your Function-Style Macros*. The package allows to write SQL queries in the data step, e.g.
|
|
```
|
|
data class;
|
|
set %SQL(
|
|
select age, name, weight, height
|
|
from sashelp.class
|
|
order by age
|
|
);
|
|
|
|
WH = weight + height;
|
|
run;
|
|
```
|

- **DFA** (Dynamic Function Arrays)\[0.2\], contains set of macros and FCMP functions which implement: a dynamically allocated array, a stack, a fifo queue, an ordered stack, and a priority queue, run `%helpPackage(DFA,createDFArray)` to find examples.
|
|
```
|
|
%createDFArray(ArrDynamic, resizefactor=17);
|
|
|
|
data _null_;
|
|
call ArrDynamic("Allocate", -2, 2);
|
|
|
|
do i = -2 to 2;
|
|
call ArrDynamic("Input", i, 2**i);
|
|
end;
|
|
|
|
L = .; H = .;
|
|
call ArrDynamic("Dim", L, H);
|
|
put L= H=;
|
|
|
|
call ArrDynamic("+", 3, 8);
|
|
call ArrDynamic("+",-3, 0.125);
|
|
call ArrDynamic("Dim", L, H);
|
|
put L= H=;
|
|
|
|
Value = .;
|
|
do i = L to H;
|
|
call ArrDynamic("O", i, Value);
|
|
put i= Value=;
|
|
end;
|
|
run;
|
|
```

|
|
- **macroArray**\[0.5\], implementation of an array concept in a macro language, e.g.
|
|
```
|
|
%array(ABC[17] (111:127), macarray=Y);
|
|
|
|
%macro test();
|
|
%do i = 1 %to 17;
|
|
%put &i.) %ABC(&i.);
|
|
%end;
|
|
%mend;
|
|
%test()
|
|
|
|
%let %ABC(13,i) = 99999; /* i = insert */
|
|
|
|
%do_over(ABC, phrase=%nrstr(
|
|
%put &_i_.%) %ABC(&_i_.);
|
|
),
|
|
which = 1:H:2
|
|
);
|
|
```

- **BasePlus**\[0.7\] adds a bunch of functionalities I am missing in BASE SAS, such as:
|
|
```
|
|
call arrMissToRight(myArray);
|
|
call arrFillMiss(17, myArray);
|
|
call arrFill(42, myArray);
|
|
|
|
rc = delDataset("DataSetToDrop");
|
|
|
|
string = catXFn("date9.", "#", myArray);
|
|
|
|
format x bool.;
|
|
|
|
%put %getVars(sashelp.class, pattern = ght$, sep = +, varRange = _numeric_);
|
|
```
