Hello, I'm trying to concatenate 12 different data sets, and they all do not have the same amount of observations, nor do they all have the same variables. Still, I want to concatenate. I've read in the 12 separate datasets with no problem. Then, when I attempted to concatenate, via: data concat;
set DN1x DN2x DN3 DN4x DN5 DN6x DN7x DN8x DN9 DN10 DN11x DN12x;
run; I encountered a problem in the log where it says: ERROR: Variable Height has been defined as both character and numeric. Then, I tried to change the variables that were character into numeric in each dataset via: data new; set original;
Height = 'NA';
Heightx = input(Height, 8.);
drop height;
rename Heightx=Height;
run; And then when I looked at the dataset, each of the data points in the variable height turned out to be all just "." instead of its numeric original data. I'm just trying to concatenate these 12 datasets together! Please help! :"(
