NA
 

in which NA are missing values,i want to predict/forecast it,i search on
internet,i found that Amelia packages can impute missing values;
i used but it giving error,how can i resolve it

library(Amelia)
t<-read.table("C:\\Users\\exam\\Desktop\\missing_ts.txt")

a.out <- amelia(t)

Amelia Error Code:  42 
There is only 1 column of data. Cannot impute

amelia(x=as.matrix(1:101,t$V1))

Amelia Error Code:  39 
Your data has no missing values.  Make sure the code for 
missing data is set to the code for R, which is NA

amelia(t$V1)

Error in colSums(!is.na(x)) : 
  'x' must be an array of at least two dimensions

is my way of predicting wrong?,if yes,then which method should i follow?
