How can I > obtain a vector of 10 elements?You actually have got first 10 elements of variable "V4" in j2 see length(j2), but as it is a factor the level attribute has retained an information about all different levels of "V4" which I presume is 1304. To get rid of these levels just use factor(j2)> > Thank you > > > > > > > > --------------------------------------------------------------- > > Fabrizio De Amicis > > > > IT Department > > Generali Information Technologies - (GIT) > > > > Centro Galleria 2, > > Via Cantonale > > CH - 6928 Manno - Switzerland > > Tel +41 91 806 6220 > > Fax +41 91 806 6298 > > E-mail: fabrizio.deamicis at git.generali.ch > > > > > > > > > ********************************************************************** > ** The information in this email is confidential and may be legally... > {{dropped}} > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://www.stat.math.ethz.ch/mailman/listinfo/r-helpCheersPetr Pikal petr.pikal at precheza.cz p.pik at volny.cz
Hi, I would like to perform hierachical clustering on data which already represents clusters means. The cluster procedure of SAS software can take into account this information through the RMSSTD option. Does anyone know a R function which can take into account the frequency of each cluster and its standard-deviation. Thanks Philippe.
Hello, Because j2 is interpreted as a factor. To get your vector of just 10 elements use as.vector(j2).
