[R] How to dynamically add variables to a dataframe

[Luca Meyer]

Hi,

I am a bit rusty with R programming and do not seem to find a solution to
add a number of variables to my existing dataframe. Basically I need to add
n=dim(d1)[1] variables to my d0 dataframe and I would like them to be named
V1, V2, V3, ... , V[dim(d1)[1])

When running the following code:

for (t in 1:dim(d1)[1]){
  d0$V[t] <- 0
}

all I get is a V variable populated with zeros...

I am sure there is a fairly straightforward code to accomplish what I need,
any suggestion?

Thank you,

Luca
