I am using some r scripts to reformat a large data set that needs to be saved into xls format.
I am getting the Out of Memory Error (Java) despite having set a large memory in the first line of the script ( on opening R and before loading any libraries) I am using R version 2.15.2 (2012-10-26) -- "Trick or Treat" Platform: x86_64-w64-mingw32/x64 (64-bit) On 64 Bit window 7 machine with 12G of ram. When I run the script to increase memory for jvm it is not increasing the memory but remaining at 244MB ( presumably the remainder of the initial 256mb once JVM is loaded... the script and out put is as follows > rm(list = ls()) > options(java.parameters = "-Xmx4096m",stringsAsFactors=F) > library(XLConnect) Loading required package: XLConnectJars Loading required package: rJava XLConnect 0.2-3 by Mirai Solutions GmbH http://www.mirai-solutions.com , http://miraisolutions.wordpress.com > print(xlcMemoryReport()) Amount of free memory in the Java Virtual Machine (JVM): 244.0936 MB How do I increase the memory? thanks [[alternative HTML version deleted]]
