[R] RES: Error while plotting matrix

You aren't using a matrix.

This is a vector so you can only use:

tvar <- rep(0,(length-tml0))
pmean <- rep(0,(length-tml0))
pmin <- rep(0,(length-tml0))
pmax <- rep(0,(length-tml0))
varmax <- rep(0,(length-tml0))
varmin <- rep(0,(length-tml0))


Why are you not using an data frame? Do you have to output this in a list()?

Assunto: [R] Error while plotting matrix



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
