“I really wish someone had shown me this function in SAS sooner, because it’s saved me a ton of time and effort,” said Brandi Rhoads as she opened her presentation at the Western Users of SAS Software (WUSS) conference in San Francisco.
Most SUG presentations are written in PowerPoint – they may even be written in Word first, and then fancied up a bit in PowerPoint – but they are rarely written in SAS. But Louise Hadden, from Abt Associates Inc, had a need to produce a lot of PDF presentations. She
