[R] Replacing dates with consecutive observations

[Indrajit Sengupta]

Hi Alina,
 
You can always write a loop in R to do this:

# A function to shift values in an vector
shift = function(y) {
 cnt = length(y) - 1
 m=vector(mode = "numeric",length = cnt) 
 for (j in 1:cnt) {
 m[j] = y[j+1]}
 m
}
 
Regards,

Indrajit

Subject: [R] Replacing dates with consecutive observations

I am working with a list of dates and I would like to replace each date with
the one that comes after, ie. 1/1/07 will become 1/5/07, 1/5/07 will become
1/7/07, etc. The number of days between my dates always varies, so I can't
just increase each one by 5 days or  so. Does anyone know of a way I can do
this in R?

thank you
