memory.limit

I ran the memory limit function in R 2.9.0 and received the 'error'
below. The memory appears to update correctly, so there's probably no
implication beyond cosmetic; however, thought I would make sure since the
function as written did not generate the same error in my 2.8.0 version of
R.

Thanks

memory.limit(size=4095)

Error in trunc(.Internal(memory.size(size))) :
  Non-numeric argument to mathematical function

memory.limit()

[1] 4095

Hello --

So, independently of any other code, the memory limit error I referenced is
not a problem. The issue I am running into now is that our analytics
group must go back to all existing code and comment out the memory limit
reference [See my example below]. I'm sure there is a quick fix. If anyone
has ideas, I would appreciate it.

Thanks

for (k in 1:3)

+ {
+    cat("hello world","\n")
+ }
hello world
hello world
hello world

for (k in 1:10)

+ {
+    memory.limit(size=4095)
+    cat("hello world","\n")
+ }

Hello Stephen,

I can confirm that I get the same behavior in my Windows machine.  Here is
a summary:

memory.limit()

[1] 2046

memory.limit(2092)

Error in trunc(.Internal(memory.size(size))) :

memory.limit()

As you described, the function reports an error but it indeed modified the
memory allocation limit.  This must be somehow related to the modification
to memory.limit() described in the release notes for Windows R version 2.9.0
(http://cran.r-project.org/bin/windows/base/CHANGES.R-2.9.0)

All: is this a bug or are we missing something?
