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?
[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 ?
