OK, you are using IDL version < 8.

You can use total() instead of mean, and divide by the number of summed items. total() does support the dimension to sum over since before IDL 8, although not as a keyword but as the second parameter.

So you could do something like

IDL> dim=1
IDL> y=total(x,dim)/(size(x,/dim))[dim-1]
