Dear list, I have been working on a report with around 60 images in it, and everything has been fine, until now. I find that the image output that is produced by odfWeave produces images that are NOT readable by OpenOffice or NeoOffice. I get empty boxes with Read-Error written in them.

Dear all, I have a list like this: l <- list(list(a=1,b=NULL), list(a=2,b=2)) I want to find out the elements with value of NULL and replace them with NA.
