Dear All,
I am facing problem with NA treatment in my financial time series data.
# data reading
aluminum = read.csv(file="alu.csv", header=T, sep=",")
fut = aluminum [,2]
spt = aluminum [,3]
# Missing Value Treatment (Linear Interpolation)
spt = interpNA(spt, method = c("linear"))
fut = interpNA(fut, method = c("linear"))
fut=fut[,1]
spt =spt[,1]
spt = interpNA(spt, method = c("linear"))
Error in interpNA(spt, method = c("linear")) : spt is not a tis object
fut = interpNA(fut, method = c("linear"))
Error in interpNA(fut, method = c("linear")) : fut is not a tis object
Then i want to convert my data into time series as following
# Making Time Series
fut = ts(fut, start=c(2006,4), frequency=305)
spt = ts(spt, start=c(2006,4), frequency=305)
Would you please guide me what is the problem with my code?
With best regards,
Upananda Pani
