Two functions can be used to subset projections objects. The operator "[" can
be used as for matrices, using the syntax x[i,j]
where 'i' is a subset
of dates, and 'j' is a subset of simulations.
# S3 method for projections [(x, i, j) # S3 method for projections subset(x, ..., from = NULL, to = NULL, sim = TRUE)
x | An projections object, generated by the function
|
---|---|
i | a subset of dates to retain |
j | a subset of groups to retain |
... | Further arguments passed to other methods (not used). |
from | The starting date; data strictly before this date are discarded. |
to | The ending date; data strictly after this date are discarded. |
sim | (optional) The simulations to retained, indicated as subsets of the columns of x. |

function to generate the 'projections'
objects.
