...] 1 R> aggregate(x, nfreq=1/3) Error in aggregate.ts(x, nfreq = 1/3) : cannot change frequency from 1 to 0.333333333333333 In fact aggregate.ts only accepts a new frequency that is a negative power of two in this example. The problem with the current test for compatible frequencies if ((ofrequency%%nfrequency) != 0) stop(paste("cannot change frequency from", ofrequency, "to", nfrequency)) is that numerical errors may cause it to fail. I suggest if (abs(ofrequency%%nfrequency) < ts.eps) instead. Martyn --please do not edit the informati...

Hello, I'm attempting to plot out a series of bar charts of recency, frequency and monetary (RFM) scores using recency as a conditioning variable so we can see the details of the FM components. My dataset looks like this: rfmCellPop{rfm_score, orecency, ofrequency, omonetary, cellpop} Where rfm_score is the composite score (cellID), oRecency, oFrequency and oMonetary are the respective parts of the score all in the range 1..5. cellpop is the number of units in the cell Not all cells are represented in the data -- most, but not all (94 out of a poss...
