I was using ar(stats) to calculate autoregressive coefficient. It works on vector z, but it will not work on vector rz <-rank (z, ties.method="average"). What did I miss? Any info will be greatly appreciated. TIA [[alternative HTML version deleted]]
Hi everyone,
I am new in R and programming. I have tried to remove the values out of
range in some variables using a loop:
1)
var <- names(est8vo[, 77:83]) # I got the variable names
> var
[1] "p16.1" "p16.2" "p16.3" "p16.4"
"p16.5" "p16.6" "p16.7"
for (i in 1:7) {
var.i <- var[i]
est8vo$var.i[ est8vo$var.i==3] <- 99
}
I got this error:
Error in `$<-.data.frame`(`*tmp*`, "var.i", value = numeric(0)) :
replacement has 0 rows, data has 215700
2) The second step would be to define the factors, but I got the same error:
for (i in 1:7) {
var.i <- var[i]
est8vo$var.i <- factor(est8vo$var.i,
levels=c(0, 1, 2, 99),
labels=c("vac?o", "s?", "no", "doble
marca")
)
}
I don't know how to do it.
Thank you in advance!

Works for my examples. But you have not specified what you actual call to ar() was. Uwe Ligges On 12.01.2011 21:17, Raymond Wong wrote:> I was using ar(stats) to calculate autoregressive coefficient.
