[R] removing lower and upper quantiles from an arry

[ONKELINX, Thierry]

You need two logical test and then combine them with & (AND) or | (OR)

i[quantile(i,.25) >= i & i <= quantile(i,.75)]

Best regards,

Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
