Hello
I am running R versions 2.13 and 2.15. One of my codes run ok on 2.13 but
on 2.15. I have tried to understand what is wrong but come up with
nothing.
Here is the code
rm(list=ls())
graphics.off()
library(R.matlab)
library(zoo);
library(xts);
library(lattice);
library(hydroGOF);
a=readMat("exemplo_narmax_Aimores_MISO.mat")
predicoes=zoo(cbind(a$predicoes[,,1]$Real,a$predicoes[,,1]$Predito),as.Date(
a$predicoes[,,1]$data))
names(predicoes)=c("Real","Predito")
ggof(obs=predicoes$Real,sim=predicoes$Predito,main="Predicao Vazao - NARMAX
MISO",
legend=c("Predito","Real"))
ggof is a function on the hydroGOF available on CRAN.
Predicoes looks like
> predicoes
Real Predito
2008-12-20 921 921.0000
2008-12-21 1002 1002.0000
2008-12-22 870 870.0000
2008-12-23 695 695.0000
2008-12-24 751 751.0000
2008-12-25 650 650.0000
2008-12-26 443 443.0000
..
which looks ok to me.
The error msg on version 2.15 is
> ggof(obs=predicoes$Real,sim=predicoes$Predito,main="Predicao Vazao -
NARMAX MISO",
+ legend=c("Predito","Real"))
Error in try.xts(x, error = "'x' needs to be timeBased or xtsible") :
'x' needs to be timeBased or xtsible
Just a remainder - there is no error whatsoever on version 2.13.
What am I missing?
Many thanks
Ed
