Hello
I have two datasets, with 4 rows and 3 columns. and I need to divide the values of one by the other.
dataset 1
Col1 Col2 Col3
Type1 T1C1 T1C2 T1C3
Type2 T2C1 T2C2 T2C3
Type3 T3C1 T3C2 T3C3
Type4 T4C1 T4C2 T4C3
dataset 2
Col1 Col2 Col3
Samp1 S1C1 S1C2 S1C3
Samp2 S2C1 S2C2 S2C3
Samp3 S3C1 S3C2 S3C3
Samp4 S4C1 S4C2 S4C3
How can I divide the values in dataset 1 by the values in dataset2:
desired result:
dataset 3:
Col1 Col2 Col3
Resl1 T1C1/S1C1 T1C2/S1C2 T1C3/S1C3
Resl2 T2C1/S2C1 T2C2/S2C2 T2C3/S2C3
Resl3 T3C1/S3C1 T2C2/S3C2 T2C3/S3C3
Resl4 T4C1/S4C1 T4C2/S4C2 T4C3/S4C3
I ws thinking of using a loop:
data result;
set dataset1 dataset2;
array type{4,3} t1c1-t1c3 t2c1-t2c3 t3c1-t3c3 t4c1-t4c3;
array sample{4,3} s1c1-s1c3 s2c1-s2c3 s3c1-s3c3 s4c1-s4c3;
%do i = 1 %to dim1(type);
%do j = 1 %to dim2(type);
result{i,j}=type{i,j}/sample{i,j};
%end;
%end;
thanks
No I am not using IML
Yes I did rename the colums in one of the dataset. Thank you for your help. It worked.
data want;
merge dateset1 dataset2(rename=(col1=_col1 col2=_col2 col3=_col3));
array var1 col:;
array var2 _col:;
do over var1;
var1=catx('/',var1,var2);
end;
drop _:;
run;
