Readers,
Data was imported using the read csv command:
dataimport<-read.csv("/path/to/dataimport.csv")
10,2000
12,2001
13,2002
15,2003
17,2004
Using the help contents for 'predict.lm' (i.e. ?predict.lm) a new data
frame was created
dataimportextra<-data.frame(x=seq(1990,2010,1))
predict(lm(dataimport),dataimportextra[,2],se.fit=TRUE)
write.csv<-(dataimportextraout,"/path/to/dataimportextra.csv")
I was expecting to see in the file dataimportextra.csv something like:
1,1990
2,1991
3,1993
...
to previously known data
10,2000
...
final extrapolated value, e.g.
20,2010
I didn't ; this suggests that I chose the wrong function! Can someone
please advise me of the correct function to use for this extrapolation
task?
yours,
