SAS-report过程介绍.docx

PROC REPORT基础一、PROC REPORT格式：PROC REPORT data= SAS-data-set options ;COLUMNS variable_1 . variable_n;DEFINE variable_1;DEFINE variable_2;. . .DEFINE variable_n;COMPUTE blocksBREAK ;RBREAK ;RUN;COLUMNS：指定输出到报表的列DEFINE：上述列的格式等COMPUTE：计算模块BREAK / RBREAK：生成合计，或报表其它类型的格式。PROC REPORT的选项Options有很多，下面介绍几个常用的：DATA= 指定做报表的数据集PROMPT= PROMPT模式NOWINDOWS= 不输出到结果REPORT = 指定一个存储的报表来生成新报表OUTREPT= 指定新路径来存放报表OUT= 建立新数据集HEADLINE 在报表变量标题和内容间生成一个水平分隔线HEADSKIP 在报表变量标题和内容间生成一行空格2 先生成一个基本的报表先生成数据：datamnthly_sales;

title1 Simple Report; column cty zip var sales; define cty / display width=6County/Name; define zip / display; define var / display; define sales / display format=6.2width=10;run;这里的define后面的/，其后面有很多选项来对变量格式，输出方式等进行设置，其选项如下：GROUP：分组显示DISPLAY：一般显示ANALYSIS：其值用于计算或统计ORDER：按其值排序显示ACROSS：交叉显示COMPUTED：其值在compute块里计算得到结果：3 使用order，按指定变量名排序显示procreportdata=mnthly_sales headline headskip ; title1 Simple Report; column cty zip var sales; define cty / order width=6County/Name; define zip / display; define var / display; define sales / display format=6.2width=10;run;结果：4 group分组显示procreportdata=mnthly_sales nofs headline headskip ; title1 Simple Report; column cty zip var sales; define cty / group width=6County/Name; define zip / group; define var / group order=freq descending; define sales / display format=6.2width=10;run;结果：5 analysis，统计量求和procreportdata=mnthly_sales nofs headline headskip ; title1 Simple Report; column cty zip sales; define cty / group width=6County/Name; define zip / group; define sales / analysis sum format=6.2width=10;run;结果：6 求多个统计量procreportdata=mnthly_sales nofs headline headskip ; title1 Simple Report; column cty zip sales sales=mean_sales; define cty / group width=6County/Name; define zip / group; define sales / analysis sum format=6.2width=10sum; define mean_sales / analysis mean format=6.2width=10Mean of/Sales;run;结果：7 如果你想让某变量的每一个值都作为一列，那就要用到across。这里要注意的是，有across选项的var，在column时后面加了一个,，从而将其后面的变量的数据直接放到across变量下。procreportdata=mnthly_sales nofs headline headskip; title1 Cross Tab Report (Across Type); column cty zip var,sales; define cty / group width=6County/Name; define zip / group; define var / across order=freq descending - Grape Variety -; define sales / analysis sum format=6.2width=10Revenue;run;结果：这里，变量variety的每一个值都成为了新的列8 BREAK与RBREAK，对分组后的报表汇总procreportdata=mnthly_sales nofs headline headskip; title1 Report with Breaks; column cty zip var,sales; define cty / group width=6County/Name; define zip / group; define var / across order=freq descending - Grape Variety -; define sales / analysis sum format=6.2width=10Revenue; break after cty / ol skip summarize suppress; rbreak after / dol skip summarize;run;结果：这里说明一下BREAK与RBREAK后面的选项：OL 汇总上方加一条线DOL汇总上方加两条线UL汇总下方加一条线DUL 汇总下方加两条线summarize 对每组进行汇总skip 加入一空白行suppress 在汇总行不显示组名9 compute块，计算统计变量，这个以后将专门介绍procreportdata=mnthly_sales nofs headline headskip; title1 Report with Row Sums (Computed Type); column cty zip var,sales row_sum; define cty / group width=6County/Name; define zip / group; define var / across order=freq descending - Grape Variety -; define sales / analysis sum format=6.2width=10Revenue; define row_sum / computed format=comma10.2 Total; break after cty / ol skip summarize suppress; rbreak after / dol skip summarize; compute row_sum; row_sum = sum(_C3_,_C4_,_C5_,_C6_,_C7_,_C8_); endcompute;run;结果：Compute块是以compute开始，endcompute为结尾，可以计算出很多复杂的数据。这里的_C*_表示第几列的变量，例如_C3_表示第三列，_C#_代表最后一行。这里的_C7_和_C8_是多余的，但不影响结果。10 proc report与ODS，以后会详细介绍。这里用ODS输出report过程结果，方法很简单，就是将上面的report代码放入ods语句之间。ods listing close;ods rtf file = c:sugi30.rtf; 上面的proc report过程代码放在这里就行ods rtf close;即：ods listing close;ods rtf file = c:sugi30.rtf;procreportdata=mnthly_sales nofs headline headskip; title1 Report with Row Sums (Computed Type); column cty zip var,sales row_sum; define cty / group width=6County/Name; define zip / group; define var / across order=freq descending - Grape Variety -; define sales / analysis sum format=6.2width=10Revenue; define row_sum / computed format=comma10.2 Total; break after cty / ol skip summarize suppress; rbreak after / dol skip summarize; compute row_sum; row_sum = sum(_C3_,_C4_,_C5_,_C6_,_C7_,_C8_); endcompute;run;ods rtf close;结果：11 report设置style，让报表更炫一点。这个以后也会详细介绍ods listing close;ods rtf file = c:sugi30.rtf;procreportdata=mnthly_sales nofs headline headskip style(header)=background=lightskyblue foreground=black style(column)=background=lightcyan foreground=black;
