Hi all,
When I run the example in RProfmem, I get:
? ? Rprofmem("Rprofmem.out", threshold=1000)
? ? example(glm)
? ? Rprofmem(NULL)
? ? noquote(readLines("Rprofmem.out", n=5))
...
[1] 1384 :5416 :5416 :1064 :1064 :"readRDS" "index.search" "example"
[2] 1064 :"readRDS" "index.search" "example"
[3] 4712 :"readRDS" "index.search" "example"
[4] 4712 :"readRDS" "index.search" "example"
[5] 1064 :"readRDS" "index.search" "example"
What do 5 the numbers in the first line mean?
In the subsequence lines I'm assuming the structure is bytes allocated : call.
I think the five numbers come from four memory allocations before example() is called. Looking at the code in src/main/memory.c, it prints newline only when the call stack is not empty. I don't see why this is done, and I may well be the person who did it (I don't have svn on this computer to check), but it is clearly deliberate. -thomas
