R help - Jul 2016 - Changing Index Labelling on x axis

Hi  I have a vector of data (for example c(2,3,4,5,4,3,2)

data<-c(2,3,4,5,4,3,2)
plot(data)

I simply want to up the index values along the x axis by 2, so that instead of
1, I have 3, instead of 2 I have 4 etc etc.  Despite ages playing around with
the axis function I can't get it to work, and keep getting weird error
messages.
 This is likely to be laughably simple but if someone can help me out I'd be
grateful

Thanks Nick W

Hi Nick,

If I understand you correctly, that should do it:
plot(x=seq_along(data)+2, y=data)

HTH,
Ivan
