SAS进阶《深入分析SAS》之数据汇总和展现
 
  1. 通过Print过程制作报表
 
  proc print <data=数据集>;
run;
选项:
obs=修改观测序号列标签
noobs不显示观测序列号
id语句在输出中取代观测序列
var选择输出的变量
where语句选择输出的观测
总结如下:
    proc print data=数据集<选项>;
        id 变量1<变量2...>;
        var 变量1<变量2...>;
        where 表达式;
        sum 变量1 <变量2...>;
        where 表达式;
        sum 变量1<变量2...>;
        sumby 变量1<变量2...>;
    run;
 
  
2. tabulate
 
  proc tabulate data=Saslib.Sales2;
    title1 
'Sales in North America';
    title2 
'TOtal Transactions';
/*
*
class为分类变量
*/
    
class Emp_ID Dept;
    var Sales;
    table Dept*Emp_ID,Sales;
run; 
  
3. 通过GPLOT过程制作图行
 
  分组变量
 
      axis1 
order=(
18900 to 18960 by 5);
    axis2 
order=(
9000 to 20000 by 1000);
        minor=(color=blue height=
0.25 number=
1); 
    symbol value=
# cv=red
            interpol=
join ci=blue;
    proc gplot data = Saslib.Sales;
        title f = 
        footnote j = r 
        plot Sales*
Date=Emp_ID/haxis=axis1 vaxis=axis2;
    run;
    quit;
    goptions reset=all; 
  
4. 增强型HTLM输出
 
      proc sort data=sashelp.prdsale 
out=work.prdsale;
        by country;
    run;
    ods html path=
"C:\Users\LEI\Desktop\data"
             body=
'prdsalebody.html'
             frame=
'prdsaleframe.html'
             contents=
'prdsalecontents.html';
    proc tabulate data=work.prdsale;
        class region division prodtype;
        var actual;keyword 
all sum;
        keylabel 
all=
'Total';
        table (region 
all)*(division 
all),
              (prodtype 
all)*(actual*f=dollar10.) / misstext=[
label=
'Missing']
              box=[
label=
'Region by Division 
and Type'];
    run;
    ods 
select ExtremeObs Quantiles Moments;
    proc univariate data=work.prdsale;
        by Country;
        var actual;
    run;
    ods html close; 
  
总结:SAS对数据的汇总和表现两种方式:一种是列表,一种是图行。通过print和tabulate过程制作各种报表和汇总报表;GPLOT过程和GCHART过制作散点图、连线图、气泡图、柱状图等多种图行;ODS输出传送系统,包括如何选择或挑剔输出对象,创建多种格式的输出文件。
