dear R wizzards: two options() related questions.
[a] options(na.action): many of my variables have missing variables, so
I would like to set a default to ignore, especially in univariate
functions like mean() and median() . alas, without na.rm=T in the
functions themselves, I always get an NA. my code is full of na.rm=T is
there a magic invokation of options with na.action that is honored by
these functions?
No.
[b] options(?): how do I get R to not prompt me for saving the workspace
upon exit, but to instead automatically save the command history
.Rhistory but not the data .RData ?
you can define a function like:
Q <- function (save = "no", status = 0, runLast = TRUE){
savehistory()
.Internal(quit(save, status, runLast))
}
and call Q(), if you want to exit.
