Dear R community, I am using a dataset and would like to define new variables using a R variable: e.g. for (i in 1:10){ dataset$i<-something } But this is not the right way, I get only one variable in "dataset"... How can I change this? Thank you! Georg. ************************ Georg Ehret Johns Hopkins Baltimore, MD [[alternative HTML version deleted]]

Hi, I tried transforming code that loads an immediate into a virtual register, and then uses that virtual register in various ways, into code that uses immediate operands instead. To my surprise, this made the register allocator produce worse code in many cases. It seems that it is splitting live intervals and spilling more. In some cases the code was better. I wonder how this could be?
