Hi all,
I have a question regarding the memory usage for the attach function.
Say I have a data.frame inputdat that I create with read.csv.
I would like to know what happens on the memory side when I use
attach(inputdata)
Is there a second allocation of memory for inputdata?
Then I'm using eval on a expression which depends on the columns of
inputdata. Is it better not to use attach function?
Thanks in advance
Christophe
