[R] Create a data.table by looping over variable names

I apologise for this very basic question, but I found no answers on the web.
I want to create a data.table with n columns, named i1 ... i'n', with only
one row with value = 100 for every variable.

I can do it "by hand":

M.dt <- data.table(i1=100,i2=100,i3=100)

but I would like to make it in a loop, as 'n' is large in my case.
