Dear R user, I have written a function which returns max,min and variation of a power (see below) Power is a given matrix(1,n)
I call the function >Variation<-VAR(p,(n-deltat)) Now the problem is when I want plot(Results[1],Results[2]). Not possible! I become the following error (in english it means: Error in as.double.default(x) :Object cannot be transformed in double) > plot(Variation[1],Variation[2]) Fehler in as.double.default(x) : (list) Objekt kann nicht nach 'double' umgewandelt werden Any suggestion? Hier is the function: #Computing variation of the power VAR<-function(power,length){ tvar=pmean=pmin=pmax=varmax=varmin<-matrix(data=0,ncol=(length-tml0)) for(i in tml0:length){ tvar[i]=i pmean[i]=mean(power[i:(i+deltat)]) pmin[i]=min(power[i:(i+deltat)]) pmax[i]=max(power[i:(i+deltat)]) varmax[i]=100*(pmax[i]-pmean[i])/pmean[i] varmin[i]=100*(pmean[i]-pmin[i])/pmean[i] Results=list(tvar,pmean,pmin,pmax,varmax,varmin) }} Thanks, Adel -- View this message in context: http://www.nabble.com/create-a-zero-matrix---fill-tp18281974p18281974.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
