inside numbers are the values for variable 4.
like Alabama 2000 1

发帖数: 2828 | 4 Alabama 跟Alaska在第二个set里面是variable name?
第一列 year 没有variable name？
你能把第二个写成sas格式的data吗？ |

Alabama and Alaska are variable names in the second data set
and year is the variable name for the first column.
I am sorry |

【在 x**********0 的大作中提到】
: yes. it is my fault
: Alabama and Alaska are variable names in the second data set

发帖数: 939 | 7 先将第二个data set换一个结构,然后再用merge语句何合并两个data set.
data dataset2;
input year @;
input v4 @;
state='Alabama';
output;
input v4 @;
state='Alaska';
output;
cards;
2000 10 100
2001 20 200
2002 30 300
2003 40 400
;
run;
proc sort data=dataset2 out=dataset2a;
by state;
run;
data combine;
merge dataset1 dataset2a;
run; |

I figured it out in the end with a different way. PROC TRANSPOSE |
