[R] R strange behaviour when building huge concatenation

Hello
I'm using some R code in order to use the model BG-NBD implementation
I'm using Java and I call R by using RCaller.
I must admit that i'm really really new to R so maybe I'm doing
something
wrong.
I use the code on this URL:  http://code.google.com/p/clv-master-thesis/
<http://code.google.com/p/clv-master-thesis/>  
This is my working Java code (a simple Junit test):
@Test
public void testRCaller(){
try {
RCaller caller = new RCaller();
caller.setRscriptExecutable("/usr/bin/Rscript");
caller.cleanRCode();
RCode code = new RCode();
code.clear();
String helper = "/dati/helper.R";
String modelNbd = "/dati/model-nbd.R";
String modelParetoNbd = "/dati/model-pareto-nbd.R";
String modelBgNbd = "/dati/model-bg-nbd.R";
String modelCbgCnbd = "/dati/model-cbg-cnbd-k.R";
code.R_source(helper);
code.R_source(modelNbd);
code.R_source(modelParetoNbd);
code.R_source(modelBgNbd);
code.R_source(modelCbgCnbd);
code.addRCode("cdData <- read.table(\"/dati/cdnow.csv\",
head=T)");
code.addRCode("names(cdData)[2] <- \"x\";");
code.addRCode("bgMleFit <- bgEstimateParameters(cdData, list(r=1,
alpha=2,
a=1, b=2));");
code.addRCode("summary(bgMleFit);");
code.addRCode("cdBgParams <- as.list(coef(bgMleFit));");
code.addRCode("t <- 39;");
code.addRCode("cdBgCe <- bgConditionalForecast(cdData, cdBgParams,
t);");
code.addRCode("(cdBgSumEstimate <- sum(cdBgCe));");
code.addRCode("(cdBgMsle <-
mean((log(cdData$p2x+1)-log(cdBgCe+1))^2));");
code.addRCode("(corr <- cor(cdData$p2x, cdBgCe));");
caller.setRCode(code);
caller.runAndReturnResult("cdBgCe");
ROutputParser parser = caller.getParser();
ArrayList<String> nomi = parser.getNames();
for (String nome : nomi) {
double[] previsioni = parser.getAsDoubleArray(nome);
logger.info("Nome "+nome+" lunghezza valori
"+previsioni.length);
for (int i = 0; i < previsioni.length; i++) {
logger.info("Valore "+ previsioni[i]);
}
}
} catch (Exception e) {
logger.error(e.getMessage(), e);
}
}

By running this code all works pretty good; now i didn't want to use the csv
file as data source; I wanted to query DB and pass data to R
As far as I know the R read.table function builds a data.frame from reading
the provided csv file. So what I did is:
I used Java in order to read the csv and I wrote this code (after I read the
csv file and for semplicity I don't write the code related to the csv
reading):
@Test
public void testRCaller(){
try {
RCaller caller = new RCaller();
caller.setRscriptExecutable("/usr/bin/Rscript");
caller.cleanRCode();
RCode code = new RCode();
code.clear();
String helper = "/dati/helper.R";
String modelNbd = "/dati/model-nbd.R";
String modelParetoNbd = "/dati/model-pareto-nbd.R";
String modelBgNbd = "/dati/model-bg-nbd.R";
String modelCbgCnbd = "/dati/model-cbg-cnbd-k.R";
code.R_source(helper);
code.R_source(modelNbd);
code.R_source(modelParetoNbd);
code.R_source(modelBgNbd);
code.R_source(modelCbgCnbd);
Map<String, Object> data = this.readCsvData();
StringBuilder userIds = new StringBuilder("ID <- c(");
long[] utenti = (long[])data.get("userIds");
int[] ordini = (int[]) data.get("ordini");
double[] tx = (double[]) data.get("tx");
double[] t = (double[])data.get("t");
int[] p2x = (int[]) data.get("p2tx");
for(int i = 0; i < utenti.length; i++){
userIds.append(utenti[i]+", ");
}
//here i check if the stringbuilder ends with, and i clean it...checkSb is
simply an utility method
userIds     = checkSb(userIds).append(");");
code.addIntArray("p1x", ordini);
code.addDoubleArray("tx", tx);
code.addDoubleArray("t", t);
code.addIntArray("p2x", p2x);
code.addRCode("cdData<-data.frame(ID , p1x, tx, t, p2x);");
code.addRCode("names(cdData)[2] <- \"x\";");
code.addRCode("bgMleFit <- bgEstimateParameters(cdData, list(r=1,
alpha=2,
a=1, b=2));");
code.addRCode("summary(bgMleFit);");
code.addRCode("cdBgParams <- as.list(coef(bgMleFit));");
code.addRCode("t <- 39;");
code.addRCode("cdBgCe <- bgConditionalForecast(cdData, cdBgParams,
t);");
code.addRCode("(cdBgSumEstimate <- sum(cdBgCe));");
code.addRCode("(cdBgMsle <-
mean((log(cdData$p2x+1)-log(cdBgCe+1))^2));");
code.addRCode("(corr <- cor(cdData$p2x, cdBgCe));");
caller.setRCode(code);
caller.runAndReturnResult("cdBgCe");
ROutputParser parser = caller.getParser();
ArrayList<String> nomi = parser.getNames();
for (String nome : nomi) {
double[] previsioni = parser.getAsDoubleArray(nome);
logger.info("Nome "+nome+" lunghezza valori
"+previsioni.length);
for (int i = 0; i < previsioni.length; i++) {
logger.info("Valore "+ previsioni[i]);
}
}
} catch (Exception e) {
logger.error(e.getMessage(), e);
}
}
As you can see the code is totally similar to the previous one except that I
don't use read.table function.
Well by executing this code I have an error. At first I thought in some
error in the Java code but I checked and no error was present
Then I tried the code in the R console. Well I have something really
strange.
Let's start from this instruction (the int array is recovered from the csv
file):

int[] ordini = (int[]) data.get("ordini");
code.addIntArray("p1x", ordini);

This Java-RCaller instruction generates this R code: p1x<-c(..........).
More exactly the generated R code is the following (be ready: it's huge):
p1x<-c(2, 1, 0, 0, 0, 7, 1, 0, 2, 0, 5, 0, 0, 0, 0, 0, 10, 1, 3, 0, 2, 0, 0,
0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1, 12, 0, 0,

7, 1, 2, 0, 0, 0, 5, 0, 4, 0);

When I execute this function in the R console I have some strain behavior;
sometimes it seems to not be executed some other time I have an error like
"Unexpected element in......" and I really can't figure where
I'm wrong...
Instead if I use the "read.table function" all works pretty good.
Can you give me any tips?
Am I wrong anywhere?

Thank you
Angelo

[R] R strange behaviour when building huge concatenation

No idea. It seems fine to me.

Perhaps a bit more information would be useful expecially your sessionInfo() 

See 
http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example
for some suggestions on forming questions.

I'm sorry but that's far beyond my expertise.  I am sure there is and it
does not "look" all that hard to read from a db but I tend to use
small data sets or existing ones that don't usually have input problems like
that .

I am using a bog-standard labtop with 4GB RAM with Ubuntu 12.10 and R2.15.2 so
if there is a limit I would have thought I'd experience it.

So I'm out of ideas though for RStudio it might be worth asking it on their
website and see if they have any suggestions about limits or if it is a
peculiarity of your setup.

Here's my sessionInfo for comparison.>
