[R] missing value where TRUE/FALSE needed

[Peter Lauren]

I am using R 2.3.0 and trying to run the following
code.

	BinCnt=round(ShorterVectorLength/10)
	BinMatrix=matrix(nrow=BinCnt, ncol=2)
	Increment=(VectorRange[2]-VectorRange[1])/BinCnt
	BinMatrix[1,1]=VectorRange[1]
	BinMatrix[1,2]=VectorRange[1]+Increment
	for (i in 2:BinCnt)
	{
		BinMatrix[i,1]=BinMatrix[i-1,2]
		BinMatrix[i,2]=BinMatrix[i,2]+Increment
	}
	
	# Count entries in each bin
	Histogram=vector(length=BinCnt, mode="numeric")
	for (i in 1:BinCnt) Histogram[i]=0
	VectorLength=length(FormerVector)
	for (i in 1:VectorLength)
	{
		Value=FormerVector[i]
		for (j in 1:BinCnt) if (Value>=BinMatrix[j,1] &&
Value<=BinMatrix[j,2])
		{
			Histogram[j]=Histogram[j]+1
			break;
		}
	}

Unfotunately, at 
if (Value>=BinMatrix[j,1] && Value<=BinMatrix[j,2])
I get the following error message
Error in if (Value >= BinMatrix[j, 1] && Value <=
BinMatrix[j, 2]) { : 
        missing value where TRUE/FALSE needed
I inserted browser() just before the call and 
(Value>=BinMatrix[j,1] && Value<=BinMatrix[j,2])
returned FALSE.

Is there a bug in my code or a bug in my version of R?

Many thanks in advance,
Peter.
