Dear R helpers,
I am a beginner at R so please be gentle :)
I have already read manuals and FAQs, with no help.
I have a monthly time series data on public debt with 40 variables,
it starts on January 1994 and ends on June 2011.
I agree with Weyland. Figuring out how to use class `ts` objects in R
is difficult. If it were easy I don't think Zeileis would have
invented `zoo`.
I am loading the data into R using read.csv and the data looks ok
when I do edit(dados):
dados<-read.csv("dadosR3.csv", header=T)
then I tried making it into a time series object, using:
dados2<-ts(dados, start = c(1994,1), frequency=12)
(See below for what that did.)
Now when I try plotting any of the variables, for example divliq.pib
(net debt), the date doesn't appear on the x axis. How can I do this?
I use
plot.ts(divliq.pib)
Try:
plot(time(dados2), dados[, "divliq.pib"] , xy.labels=FALSE))
also the function names() doesn't work, which would be important
since I have so many variables.
names(dados2)
Read the help page again(?). "A data frame will be coerced to a
numeric matrix via data.matrix."
The names function only works for lists and name vectors. Try colnames()
NULL
I am using R.2.13.1
Thank you very much.
