[R] How to add values to an array at any position.

[Witold Eryk Wolski]

Hi,

How to add values to an array at any position.
Asking because of the following:
e.g.

y<-c(0.1,NaN,0.2,NaN) #or data frame


x<-na.omit(y)

take some columns from x and
do some computation with functions which do not allow NaN 's.

After the computing add NaN's at positions stored in
attr(x,"na.action")
of the result vector.
